You'd think that if they were worth their salt they would make something like what you need to do as simple as possible - and would tell you how...

It's probably nothing more than appending some "id=123456" scenario to your outbound links, but they must provide that info.

That being said, if it **truly** must be entered manually, then you may not be able to insert variables as a safety (anti form-spam) feature.
