Re: [ cf-dev ] isdefined

[Stephen Moretti (cfmaster)]

Paul,
How can I check to make sure that if the formvariable is null I trap 
the error and do something.
I have used isdefined, NOT is defined, eq "" etc etc but the code 
always crashes with a variable not defined error.

Ah right - had a play on the site - incidently those nasty java applet 
for simple rollovers should go in the bin and be replaced by a weeny bit 
of Javascript and two tiny gifs.

What you need is probably : 
ListFindNoCase(Form.FIELDNAMES,"SelectSize"&Replace(ItemIDPK,"-","_","ALL"))

To check that you actually have a size for that item number back from 
the form.

Regards
Stephen
