Validation vbscript to ASP

Expand Post »

Im having problems with getting the page to stop progressing to the asp one when the user enters the text outwith the limits i.e. no data entered. Could anyone give any guidance?

Cheers

Re: Validation vbscript to ASP

value = "" needed to be initialised and the onSubmit isnt needed and it works a treat.

#
validation = True also needed at the start instead of False.
