Facebook Form not working with Coldfusion8

I have a simple contact form setup in a Facebook fbml application box. When the name and email are sent from Facebook to my website, I receive the following error:

Form entries are incomplete or invalid. * 1289913801.2738

I have simplified everything so the only thing on my website's page is:

<cfoutput>#form.firstname#</cfoutput>

Here is my form:

<FORM action="http://www.scobc.com/fbml/download_report.cfm" method="post" target="_blank">

<input type="text" name="firstname" value="First Name" size="25"/>

<input type="text" name="email" value="Your Email Address Here" />

<input type="hidden" name="catagory_id" value="35" />

<input type="submit" name="operation" value="Download Now" />

</form>

Any idea why I am getting the error code?
