hello.
I need to activate (show or hide?) a FORM's submit button IF a condition exsists or does not exist (someone voting on a sample poll already ... means HIDE the submit button so they cannot vote again).

Any ideas how / if / I can do this using CF!? else!?

Thanks much!
Richard

If you want to do it on the Client side, you need JavaScript.

Otherwise, you could use the following ColdFusion code:

<cfparam name="session.voted" default="false">
<form>
<input type="text"><br>
<cfif session.voted is false>
<input type="submit">
</cfif>
</form>

Put this line on the action page of the form:
<cfset session.voted = true>
