Hi please help me, im trying to make a program that only accepts numbers. What can I do to disable letters and special symbols? for example, I enter "sffsdttsfsjfs" / "!%#^$*$(" then the program would prompt that "Error: Letters and Special Symbols are not allowed"
I saw a thread here, but the solution is too complicated for me, a freshmen student, to understand, maybe theres a 1-5 line code for this? help me please
