Help for multiple text * var.

Question

I needed to multiply a number of rows based on a var. See line 74-76 of the code. Does anyone know why output is coming out NaN?
PS: What means NaN?

Answer 1

NaN stands for Not a Number, meaning that the variable you are entering is not a number (it's quite self explanatory). I think the problem is that you're trying to test if a string equals an int, which does not bode well with JavaScript. Try changing 1 and 2 to "1" and "2", as testing to see if they are equal to a string may work.

Hope this helped! d:
