Download a File on Web Port

How can I make it so that this protocol does its thing, then writes it to one of various file types, and offers the link for download, but does not retain the file afterwards.... I am writing it to \$(Temp); I have Temp specified as a Temp File int he parent protocol.

I have tried defining the results under the Parent Protocol's "web service" tab as:

@Temp, \$(Temp), '\$(Temp)', and Temp.

None of these have worked, it keeps showing up as having no results. Any help would be appreciated.
