Stateless Form Submission and input.ID

I have a stateless form that submits data. Part of this data is a url link to the record created by the stateless form. The problem is, in constructing the link in the stateless form OnSubmit script I'm using "input.ID". This value is being assigned null in the record. I was under the impression that creator might hold a value for ID in case the stateless form called for it. I guess not. Now I'm left with having to script and assign my own "ID" to reference this record.

Am I totally wrong, or is this another let-down built into the system?
