I think that there is an error with the test for parseInt for Javascript Foundations.

hi Brooke Casey , actually you're very close to the right answer already. you created the variable correctly and you're also using parseInt.

however when we look at the question (btw: it's always good to post the full question when you start a topic so we can see your code in a context): A variable named "boxWidth" already exists with a value of "640px". Create a new variable named "numWidth" and use the "parseInt" method to extract the numeric value from boxWidth's string value.

the question wants you to use the already existing value which is stored in a variable and not to write the value of the variable into the function. if you already have code in a variable it's good to use the variable instead, so if you later want to change something you only need to change it once (in the variable) instead of changing the 640px manually on multiple places.

so to round this up, I hope I explained it well, here's what the full code - using the existing variable - would look:

var numWidth = parseInt(boxWidth, 10);

hope that helps and have a nice day ;)

Hi Brooke,

Hint: if you put a value into a variable you might as well use the variable.

Thanks Alex and Jeff, this answers my question about this also. However, the videos don't touch on this, in fact is shows us that if you don't use a number at the beginning of the parenthesis, the code won't run. I'll give this a shot and see how it goes.

Thanks again, Tracey
