Need help with tax calculator

[joedoe]

HI,

nice idea, I thought the same before, but what if somebody copies the price and pastes it to the inputfield?

I think, it is very easy to build the func for one regional setting, but to fit every possibility there have to be some guidelines how to use it.

So long,

Mega

This should be the function to validate the input to numbers only:

Func ValidateInput()
    $errorflag = 0
    $errorlog = ""
    If $qualitys < 0 Or $qualitys > 9999999999 Then
       ;Error code here
    Else
       ;
    Endif
Endfunc
