1st UDF and questions

Question

Ok, I got some code working on a page, and would like to now
see about
putting it in a UDF...
The UDF right now looks like:
<cffunction name="classSort" output="false">
<cfargument name="eventType" type="string"
required="yes">
<cfset temp_var=1>
<cfloop list="arguments.eventType" delimiters=","
index="i">
<cfset full_var_temp_var=#i#>
<cfset temp_var=temp_var+1>
</cfloop>
<cfswitch expression="full_var_1">
<cfcase value="f">
<cfif var_temp_2 gte 15>
<cfif rates.C gte 2>
<cfif rates.B gte 2 or rates.D gte 2>
<cfif rates.A gte 2 and rates.B gte 2>
<img src="images/A1.gif" width="94" height="29">
<cfelseif rates.D gte 2 and rates.E gte 2>
<img src="images/C1.gif" width="94" height="29">
<cfelse>
<img src="images/B1.gif" width="94" height="29">
</cfif>
</cfif>
</cfif>
</cfif>
</cfcase>
</cfswitch>
</cffunction>
And I'd be passing arguments in the form of functin(f,30)
What I'm trying to do is get the image filename sent back so
I can display
it on the page.
Am I on the right track here???

Answer 1

Well, I changed the function to:
<cffunction name="classSort" output="false">
<cfargument name="eventType" type="string"
required="yes">
<cfif eventType gte 15>
<cfif rates.C gte 2>
<cfif rates.B gte 2 or rates.D gte 2>
<cfif rates.A gte 2 and rates.B gte 2>
<cfset retImage="images/A1.gif">
<img src="images/A1.gif" width="94" height="29">
<cfelseif rates.D gte 2 and rates.E gte 2>
<img src="images/C1.gif" width="94" height="29">
<cfelse>
<img src="images/B1.gif" width="94" height="29">
</cfif>
</cfif>
</cfif>
</cfif>
<cfreturn retImage>
</cffunction>
Now my question is, in the code that's calling the function,
the image isn't
displaying..... I tried <img
src="#classSort(foilCount.recordcount)#">
Is that not correct?
