Here's a common use for CFParam ... at least for me ... Let's say I have a form that can be used either for updating existing data OR for inserting new data. If the form will function as update, I'll want to display the existing data, such as: cfinput type=text name=fname

CFSET - expicitly set the variable to the value specified CFPARAM - if the variable specified already exists then leave it alone; if it doesn't already exist then create it and set it to the value of the DEFAULT parameter. an easy example: you fill out a form and have, say, a checkbox. If the
