I can't get a variable to display, if I dont use cfparam to put a default value of blank in order to declare the value I get an error, and if I use cfparam this way each time a form is submitted the page reloads and the variable is empty due to the declaration??

Yes <cfparam...> does not rewrite a variable. The documentation would
have a good explanation of this. The purpose of <cfparam...> is to
include implicit *if* logic. If this variable does not already exist
then create it with this value.

cfset
