You'd probably want to build your merge list dynamically:
<cfset mergeList = "" />
<cfloop from="1" to="6" index="i">
<cfset thisFile = "D:\uploads\FAD\#evaluate('cv' & i)#" />
<cfif fileExists(thisFile)>
<cfset listAppend(mergeList, thisFile) />
</cfif>
</cfloop>
Then use #mergeList# as the "source" attribute for cfpdf since it
should only include files that were uploaded and exist on the server.
I'd avoid using evaluate() if possible though, I included it here for
your existing variable names but you could do better using a structure
to store the filenames instead.
