I mean I can simply convert this String to an Integer, but I doubt this would help, cause a String can get converted to an Integer. (Like A is 65 I think) So how can I be sure that the user typed 65 and not A ? Marcus [EMAIL PROTECTED] schrieb: > > Are you kidding? Dude, everything typed in an HTML form is a string.
