ColdFusion how to get a message from cfcatch

I'm doing a cffile upload, and want to trap any errors in the MIME type. I wrote this code:

 <form 
 enctype= "multipart/form-data" 
 method = "post" 
 name   = "templupload"  
 action = "frag2.cfm">

<cftry>
   <cffile action = "upload"
    destination   = "#session.exploc#"
    fileField     = "form.theupload"
    mode          = '666'
    accept        = 'html'
    strict        = 'true'
    result        = 'ss'
    nameConflict  = "Overwrite">

    <!--- bad mime type files --->
    <cfcatch type = 'any'>   
       <cfif FindNoCase("The MIME type or the Extension of the uploaded file", cfcatch.message)>
       <cfoutput>
          <script>
             document.getElementById('tmpl').innerHTML = "error";
          </script>
       </cfoutput>   
       </cfif>
    </cfcatch>

 <cfthrow type="any" message="got an error" />         
</cftry>

When I try to upload a wrong MIME type, it does not load, which is good. The form is submitting which is not good but I'll deal with that later. My problem now is I have been unable to get a message about the error to show up anywhere. I have tried the following:

<cfcatch.message = 'error'; 
<script>alert('error');</script>
<script> document.getElementById('tmpl').innerHTML = "error";</script>
   <!--- this 2nd script does not work regardless of whether the tmpl
         id is on the original page or the target page --->  
<cfoutput> error </cfoutput>
<p> error </p>
<cfthrow type = 'any' message = 'error' />
<cfdump var = "#catch#"  or var = '#catch.message#"

I have tried all these inside and outside of the cfcatch tag, but always within the cftry tag. All of these approaches were in the research I did, but none of them are working for me.

Can anyone tell me what I am doing wrong here?

Are you looking for something like this?

 <cftry>

 <cfcatch>
      <cfset request.error = cfcatch.message>
 <cfcatch>

</cftry>

Then much much later

<cfif request.keyExists('error')>
    <cfoutput>#request.error#</cfoutput>
</cfif>
