Disappearing sub form

[niccig]

I have an open form (frmPayDetails) that I enter in pay details, sometimes I need to keep that form open and swap to a different form (frmProject) to enter Project Details. I need to go back and forth frequently so I keep both forms open.

My problem is this:
FrmPayDetails has 2 subforms - subfrmpay and subfrmcalc. When I swap back to frmPayDetails from frmProject, subfrmcalc has disappeared. If I close frmPayDetails and open it again, it comes back but I don't want to close it each time. How can I keep this subform on the screen at all times?!?!?!

Much thanks,
Nicci

Figured it out

The subform that kept disappearing was based off the other subform, and when that didn't have any data, the query wouldn't work. I changed the structure of the form, put in an Update button and it works fine.
