Use a hidden field instead of relying on the button value. Button values are only present if the user actually clicks the button. Using the form submit event via code or even the user pressing enter instead of clicking on the button will result is no button value being posted.

If I may be a bit pedantic.

<cfif StructKeyExists(form,"fieldnames")>

I've heard of  isDefined() giving false responses.

HTH,

As far as I know, isDefined("form.someFieldname") is practically equivalent to  structKeyExists(form,"someFieldname").
