I assume this is what I needed to do, using player.AddItem .

I used TES4Edit to find the FormID, opened the console, typed player.additem (number) 1 (quantity).

I get a message in the console along the lines saying not found for parameter id....compiled script not found.

I'm not a modder so easy on the modder techno-babble.

I need this to replace an item I lost in an uninstall that I didn't know was part of the mod during troubleshooting.

That means the form id number you entered was wrong. The first two digits are the mod index, that is most likely what was wrong, find the mod in OBMM/Wrye Bash and see it's load order index (it is a hexadecimal number, so it may have a number and a letter), put that as the first two digits, and the rest of the code after that.

I used an item code 0E01BFB7 in Fallout 3 just a while ago for example, "0E" being the mod index (15th mod in my load order).

bleh several sites that gave that info never mentioned it.
