[AccessD] Form not refreshing--sometimes

Allrighty...If anyone is paying attention to this problem, I've got
something to add. Instead of the line to requery the subform, I added
the line "DoCmd.OpenQuery "qryMonthly" just to see what would happen.
The query opens up with all the proper data, according to the parameters
that I have entered...I tested it with different data too.

I of course, really don't want to do it this way, but what exactly is
it telling me? I'm not sure. Maybe there is a problem with my subform
control? But, if so, why does it work sometimes? Again I say,
"AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!!!!!!!!!!!!"
