Silent Remote Sending not sending data

I’m trying to use Silent Remote Sending to send data from FSCF #1 to FSCF #2. I see in the FAQ how to send to a 3rd party form, but I’m not real clear on how to send to a second FSCF form. Here’s an example of how I’m renaming my fields…

Query string fields to rename: from_email=2email

I’ve enabled Redirection and set the Redirection URL and Silent Remote URL to the same URL.
