Form Error Handling

[Guest_imported]

Hi E$verybody,

I'm trying to work out how to have an Input Box that can validate

If someone types in nothing it'll display an error message.
I'm trying the below but its not working?

SrchStrLen = len(SearchString)

if left(SearchString, 1) = "" then
SrchStrLen = SrchStrLen-1
reponse.write "Error Error"
end if

if you're going to do it server-side:

SrchStrLen = len(SearchString)

if SrchStrLen = 0 then
response.write "Error Error"
end if

you can also do it client-side with javascript, but i'm not so good with javascript, can someone else provide that solution?

Here is a nice little script I have used before.
