<cfif isdefined is not working

I am using cold fusion 8 to develop forms. I need to check if user has entered a value of type "text". If not then a message has to Cfoutput. i am using the following code:

The problem is even f nothing is entered in the Question Field, the message Enter question is not being displayed. Its as is the <cfif not isdefined("form.question")> is not at all being recognised.
I also tried <cfif not isdefined("form.question_now")>

Please help.

Welcome to TSDN!

Try using cfparam and the default attribute instead. Then you can check for the default value (which you usually set to nothing - empty string).

re: <cfif isdefined is not working

Can you also post your form code?

coz I think <cfif not IsDefined("Form.whatever")> is fine, the problem
may point to the form submission. Check your form method, are you actually using post instead of get; you should also check which template you submit the form to??
