How to force user to provide valid input
Hi ,I am trying to force the user to give a valid entry: I display a modal window, and ask to give a value.If this value is a string different than "" , then the code should go on using the value given. If not , the script should hang on or prompt the user to give correct input.I tried using a modal window + hiding the OK button, but somehow, it does not do the job (see attached code).Please help....
