OK... I think we're close, but I still seem to be having a problem. Strangely, it seems as if perhaps the form results email is being sent before it is ready to reference the uploaded file. Here's what is happening.
If I upload a file, the form results email shows nothing in the uploaded file link we made. However, if I send another email immediately after the first, but do not include an uploaded file, the form results email lists the previously uploaded file in the corresponding file link.
It's almost as if it couldn't see the uploaded file variable until after the first email was sent. (I tried it with and without the "unset" session code.)
Hopefully that makes sense. I'll attach my files in case it helps to take a look at them. Thanks so much for you assistance.
