Um, thanks for the reply, but you must not have read my discussion at all, as I already found I can not pull from the files array because recordings (WebRTC) is sent back to the server as a blob. So, the normal files array are all null. All are empty.

So, I moved on to checking it at form submit. Yet, I can't find any documentation or even a hint of how I do the check at submission.

And, as a developer, it should not mean I have to read code, figure out hooks, figure out what classes to extend and what functions to override, without documentation. Otherwise, I'm trying to build an engine from a million parts without a schematic. Yes, I'll eventually get it, but if only I had t schematic. I hope you understand my parable.
