Help!

I don't understand why var numWidth = parseInt("640", 10); is not working for code challenge task one on parsing numbers from a string. Can anyone help. This is truly starting to frustrate me.

</script>

You actually want to pass the string variable as the first argument into parseInt() likse so:

var numWidth = parseInt(boxWidth, 10);

Thank you so much. I was wondering what was to reference the initial variables. I was on the right track. But this was very tricky to me. Thanks again. I really appreciate it.
