Subform with query source doesn't display correctly (1 Viewer)

I have a subform on my form that is "filtered" by comboboxes. The subform will display records after selecting criteria from the comboboxes, but it doesn't display all the records. After the records are displayed in the subform, I open up the source of the subform, which is a query, and that displays all of the information correctly. In fact, when I print a report based on the query, it'll display all of the records correctly too!

I don't have any filters set up. It's supposed to display the query in its entirety, but it doesn't. It only displays some of them.

Any ideas?

You haven't given us much to go on. Does selecting a value in the combobox modify the underlying sql? How does it work? Does it modify the sql of the main form? We need more information.
