Please let us know what you're working on. A link to the course page would help, and also show any code you have written.

SELECT addresses "Maple" ||', '|| "White Plains" || ', ' || "NY" || ', ' || "10605" || ', ' "USA" AS "address";

You need to use column names instead of literal strings for the data values. The instructions tell you specifically which column names to use. And check the strings being used to add the spacing and punctuation. It looks like you may have a comma instead of a period in one, and an extra comma (where only a space is needed) in another.

You also still need the "FROM" clause that names the table being used as the source.

You need to concatenate all the values with double pipes IN ORDER. You're basically adding words left to right to build a final string value which you're storing in a single column named to_field.

Think of it similar to math:

first_name + space + last_name + space + '<' + email + '>'

... then recall the SQL syntax where + = || and space = ' '... replace the above logic with proper SQL syntax and you get:

first_name || ' '  || last_name || '<' || email || '>'

.. then you've gotta name the new column AS to_field and wrap the statement up. I think you can do it from there.

Thanks so much guys. Im on the second challenge though. Still having trouble with it.

Did you make all the changes I suggested? What does your query look like now?
