Where is the ID?

I want to enter an item into a recipe to be analyzed, but the analyzer doesn't recognize it. I've found it in the database, but cannot see an ID number anywhere......

I'm not sure what it's called, but look up at the top of your browser where the http://www.etc. is and at the end of all of that you will see a number like [12345].  That is what you use.  It took me a week to figure that one out.

AWWWWWWWWWWWesome! You rock!

Yeah that took me forever to figure out as well, and I ended up having to post here to find out too. It should definitely be made clearer where to find the ID in the instructions.
