Can't pass the last Test (argentinaRecordsAreFormattedAndConverted)

On this exersice, Im totally blocked and can pass the last test, I put the the two functions "usdToArgentinePesoConverter" and "argentineCurrencyFormatter" together in the same function by using "andThen", but after in the return statement I don't know what to do, if I use the new Function gathering "usdToArgentinePesoConverter" and "argentineCurrencyFormatter" I can see the new price in Peso Argentin, but the exercise is not validated by the test, and what is homeValueIndex, and How to use it with the new Function ?

If someone has already did this exercise, I would appreciate some help, Thank you very much

public static List<String> getPricesConvertedForArgentina(List<HousingRecord> records) { Locale argLocale = Locale.forLanguageTag("es-AR"); // This fluctuates and is hardcoded temporarily BigDecimal argPesoToUsdRate = new BigDecimal("15.48");

```// TODO: These functions are in working order, but separately they don't match the single Function signature expected
Function<Integer, BigDecimal> usdToArgentinePesoConverter = usd -> argPesoToUsdRate.multiply(new BigDecimal(usd));

Function<BigDecimal, String> argentineCurrencyFormatter = price -> {
Currency currentCurrency = Currency.getInstance(argLocale);
NumberFormat currencyFormatter =
NumberFormat.getCurrencyInstance(argLocale);
return String.format("%s (%s)",
currencyFormatter.format(price),
currentCurrency.getDisplayName()
);
};

Function <Integer, String> testConverter = usdToArgentinePesoConverter.andThen(argentineCurrencyFormatter);

return getConvertedPriceStatements(records,
// TODO: Correct this.  It should to convert AND format.  However, there is room parameter wise for only one Function...hmmm.
//homeValueIndex ->
testConverter
);
```

}

I can see this error message:

Expected: iterable containing ["First is \$1.00 (USD) which is \$15,48 (Argentine Peso)", "Second is \$2.00 (USD) which is \$30,96 (Argentine Peso)"] but: item 0: was "First is \$1.00 (USD) which is \$15,48 (peso argentin)"

hi Philippe Doreau ,i know its not that easy and it took time from me to solve this challenge

here's my code

```  public static List<String> getPricesConvertedForArgentina(List<HousingRecord> records) {
Locale argLocale = Locale.forLanguageTag("es-AR");
// This fluctuates and is hardcoded temporarily
BigDecimal argPesoToUsdRate = new BigDecimal("15.48");

// TODO: These functions are in working order, but separately they don't match the single Function signature expected
Function<Integer, BigDecimal> usdToArgentinePesoConverter = usd -> argPesoToUsdRate.multiply(new BigDecimal(usd));

Function<BigDecimal, String> argentineCurrencyFormatter = price -> {
Currency currentCurrency = Currency.getInstance(argLocale);
NumberFormat currencyFormatter =
NumberFormat.getCurrencyInstance(argLocale);
return String.format("%s (%s)",
currencyFormatter.format(price),
currentCurrency.getDisplayName()
);
};

Function<Integer, String> indeedToArgentineCurrencyConverter = usdToArgentinePesoConverter.andThen(argentineCurrencyFormatter);

return getConvertedPriceStatements(records,
// TODO: Correct this.  It should to convert AND format.  However, there is room parameter wise for only one Function...hmmm.
indeedToArgentineCurrencyConverter.andThen(
(String homeValueIndex) -> String.format(homeValueIndex, homeValueIndex))
);
}
```

Thank you Fahad for your help, I will try to know to understand the logic : )

You saved me, thanks!

The code can a be a little bit simpler like below, and it works with the lambda

```    Function<Integer, String> argentinConverter = usdToArgentinePesoConverter.andThen(argentineCurrencyFormatter);

return getConvertedPriceStatements(records,
// TODO: Correct this.  It should to convert AND format.  However, there is room parameter wise for only one Function...hmmm.
argentinConverter.andThen(
homeValueIndex -> homeValueIndex
)
);
}
```

I was also banging my head against this one for a while. The problem indeed turned out to be the non-breaking space as suggested above, so thank you to Nick for that.

To solve this I modified the getPriceConversionForRecord method as follows:

```  public static String getPriceConversionForRecord(HousingRecord record, Function<Integer, String> priceConverter) {
NumberFormat usFormatter = NumberFormat.getCurrencyInstance(Locale.US);
return String.format("%s is %s (USD) which is %s",
record.getRegionName(),
usFormatter.format(record.getCurrentHomeValueIndex()),
priceConverter.apply(record.getCurrentHomeValueIndex())
).replaceAll("\u00a0", " ");
}
```

This replaces all non-breaking spaces with normal spaces, allowing the test to pass.

i followed all steps exactly but i still have the same error : iterable containing ["First is \$1.00 (USD) which is \$15,48 (Argentine Peso)", "Second is \$2.00 (USD) which is \$30,96 (Argentine Peso)"] but: item 0: was "First is \$1.00 (USD) which is \$ 15,48 (Argentine Peso)" Anyone pls help me ?

I'm having the same issue, seems like somehow there's a space between the '\$' sign and the integers and that's why the perpareSubmission can't recognize the String as working

Actually, it's (\$--> <--15,48) not a "space" it's something called "U+00A0 : NO-BREAK SPACE [NBSP]" character. So you can pass this challenge by replacing the code in src/test/com.teamtreehouse.challenges.homes/MainTest

from:

"First is \$1.00 (USD) which is \$15,48 (Argentine Peso)",

"Second is \$2.00 (USD) which is \$30,96 (Argentine Peso)"

to:

"First is \$1.00 (USD) which is \$ 15,48 (Argentine Peso)",

"Second is \$2.00 (USD) which is \$ 30,96 (Argentine Peso)"
