Let me phrase the question differently.

I have a grid. The RecordSource has 16 records and is unfiltered. The record pointer is on the first record. There are a number of columns. The controlsources are all correct, and refer to fields in the grid.

But no records show. When this happens, I am not able to do anything to make any records show either (and would welcome suggestions)

And this happens sporadically and inconsistently.

Guesses?
