Changing Record of Subform in MS Access

Question

I have a form that contains 4 subforms. The first subform gets data based on a selection in a combo box on the main form. The second subform gets data based on the first subform, and the third and fourth subforms get data based on the first.

It's a database contain information on research grants. I want to be able to pull up certain data based on a person's ID (multiple records to a person) or by the title of the grant. Names are working fine, but searching by title is giving me a hard time.

I've tried setting first subform's Record Source with a .RecordSource ="" line, but nothing updates at all when the code runs (the code is in the AfterUpdate event of the combo box containing grant titles). This one has me sort of stuck; I'm not sure if the dependencies among my forms have something to do with it.

更新记录源后是否放入Form.Refresh？
