Apply Filter in subform

Hello
I have a main form and a subform.
The subform contains several records wich have the field Date.
Using a combobox that groups the dates, I intend to filter , in the
subform,only this or that date, so I can see only the records wich have the
same date.
So far, I have the combo and the code Docmd.ApplyFilter "qryxyz" in the
afterupdate procedure, but I can´t make it work.
I have no idea if this possible to build .Can someone help ?

Thank you for reading my message
Paulo
