Thanks for the reply, John ...

The two cbo's have the same table for the ControlSource, but different tables for the RowSource. Also (and this may be it), the cbo that works initially has a relationship between it's ControlSource and RowSource tables, whereas the one that doesn't work has no relationship between it's two sources ...

If a table is at eof(), I can't get the dropdown to fire on a cbo on a page, but if I simply click on one of the cbo's that is on the form, then click back to the cbo on the page, it works fine. This happens regardless of the "status" of the form cbo (it could have it's table at eof() and it doesn't seem to matter). Thinking that perhaps it had to do with a refresh, I've tried putting refreshes in several places, all to no avail.
