Anyone know how to calculate a percentage from form variables. I have a simple
quiz (five questions) with multiple choice answers. I have the correct answers
set using cfset on the processing page. However, I need to run a percentage so
the display shows something like: Score: 80%.
Here is the form page:
<cfoutput>
<form name="Test" action="A1.cfm?CID=#URL.CID#" method="post">
