I have a hidden Input form that has a value of 78, I am using javascript to validate that the amount the User entered in a new Input form is greater than the amount in the hidden form. But this is failing when a user enters stuff like 0775 or 000745. Is there a way I could remove the leading o's zeros and then do the validation. <cfinput validate integer> allows entering of leading zeros, I want to remove the leading zeros. Is it possible?

Thanks

Multiply by one removes the leading zeros. <CFSET foo = 1 * userData)> Be sure to do this after you verify that userData is numeric.

Regarding ensuring the value is numeric, be careful of using the js parseint, parsefloat or whatever those functions are called. They don't always return NaN (not a number) for non-numeric strings.
