Hmm your cfif for testing if data is validated is missing a lot of code so I'm not sure if you copied and pasted but if so then thats the case. Also please share with us what your error actually was. You'd be amazed at how much that can help us solve your problem even quicker. Try this:

<cfif IsDefined("Form.Submit")>
      <cfif Len(Trim(Form.Pmm)) NEQ 0>
           You selected a value from the select list.
      <cfelse>
           You did NOT select a value.
      </cfif>
</cfif>

That should get your code working. Remember when using a select drop down by default it only returns one value so there is no need to test for it with .value (this ain't JavaScript;)). Also don't put pound signs where they aren't needed for example you don't need them in your cfif statement, makes for ugly code. Frown

Because a select only returns one value we just reference it as we would any other form variable, by its name.

Let me explain the code above. What its saying is trim any whitespace and then give me the length of the value selected in the drop down. If it has a length (anything but a length of 0 - NEQ 0) that means the user selected something (value="someone's email") if not then the else statement executes because there is a length of 0 (value=""). Hopefully this all makes sense. Good luck. Smile

Error is
1Form," on line 480, column 16, is not a valid identifer name
The CFML compiler was processing:

an expression beginning with "1Form.pmm", on line 480, column 16.This message is usually caused by a problem in the expressions structure.
an expression beginning with "Trim", on line 480, column 11.This message is usually caused by a problem in the expressions structure.
an expression beginning with "Len", on line 480, column 7.This message is usually caused by a problem in the expressions structure.
a cfif tag beginning on line 480, column 2.
a cfif tag beginning on line 480, column 2.

My code is
<cfif IsDefined("Form.Submit")>
      <cfif Len(Trim(1Form.Pmm)) NEQ 0>
           <cfoutput>success</cfoutput>.
      <cfelse>
            <cfoutput>notsuccess</cfoutput>.
      </cfif>
</cfif>
Still it is giving me above error

There is no such thing as 1Form. It has no meaning in ColdFusion and that is why its throwing that error. Just leave it as Form.Pmm and it will work trust me. Pmm is part of the Form scope so thats why you say Form.Pmm and not 1Form.Pmm. Make sense??

No you didnt at all, its great that you help out. By no means you are not intruding. Smile

I just hope that jampu understands that when you want to reference a form variable its in the Form scope and not 1Form as that is not a valid structure. Maybe why hes confusing that is because his form is set too name="1Form".
