Very Very Strange Problem

Question

I'm pretty good at action script, but this one is killing me,
it's a stupid problem to have.
I'm just gonna paste all my code, hope that's okay..
Sometimes the variable "CurrentImages" gets set using this
"CurrentImage = CurrentImage-(-1);" other times it gets set using
this "CurrentImage = CurrentImage-1;" And very few times, it gets
set using this "CurrentImage = this._name.toString().substring(4);"
When the last method is used to set the CurrentImage
variable, something strange happens to the if statement
"if (CurrentImage<Data.n) {" it says it's false for
numbers 5 to 9, and true of any other number that are less than
Data.n.
At this time, Data.n is 46, and 7 should be less than 46, it
should be true, but it gives false... and I don't know why.
If anyone could help me solve this, I will be very grateful

Answer 1

In your last method of calculating CurrentImage, CurrentImage
becomes a String and not a number. And so, it does the comparison
in an alphabetic manner, ie see which first digit is less, if same,
next digit, etc. So, "46" would be less than "7" because 4<7. To
remedy, use the Number conversion function:
CurrentImage = Number(this._name.toString().substring(4));
It gives the numerical value of the given expression.
