That makes sense, thanks. In this instance, realistically the only actual chance of error is the user inputting something wrongly in step 1. By the time it's gone through steps 2-4 (which do have checks in place, and I'm working on verifying the input during step 1) it's just following a long-established business process (which has been working flawlessly for, oh, ten years or so).

Followup question: is there such a thing as too much error handling?
