Function from FormA sets combo box value on FormB but does not update SubformB

[cbsull]

I have two forms (FormA, FormB) with combo boxes (cboA, cboB) that control the record being shown in the subforms (SubformA, SubformB). I have written code and attached it to the "AfterUpdate" function on the combo boxes and this works perfectly.

Here's my problem....

I have a button on FormA that, when clicked, opens FormB, assigns the value in cboA to cboB and closes FormA. Unfortunately, I can not figure out how to have SubformB automatically update based on the new value assigned by code to cboB.

I've tried .Requery, "After Update/Change/Dirty/etc." on cboB, "OnOpen" on FormB, and moved the code from cboB "AfterUpdate" to ButtonA "AfterClick" and nothing seems to work.

I need the user to use buttons to navigate through various forms displaying information for the same record. I also need to give the user the option to switch the record using the combo box. Does anyone know how to do this? Is it possible to use code to update the value in a combo box and then have the record in the subform automatically change?

After the value is stored in form B combo box, requery form B.
