How do you report hours that vary week to week? (update)

I picked up part-time shifts as a sales associate and I am confused about how to report them. I would rather hear the honest version than the polite one. The form asks for gross earnings, which I do not see until later.

In my state the question was about the week I worked, not the week I was paid. Read the wording on your form carefully, or ask the claims line.

The claimant handbook has worked examples for part-time pay. Mine was clearer than the phone line.
