Requery does not work when used in a SubForm

[Tony]

I have a form that contains a Combo Box (Location) that 'After Update' runs a
macro that requeries the Combo Box (SubLocation). It works fine as a form,
but when I try to use it as a SubForm, I get a "You can't use the
ApplyFilter Action on this Window" error. Help, I am not that familiar with
any coding but any help would be appreciated.
Thanks in advance,
Tony

I dont know what you wrote in the macro or why you created a macro, but try
writing on the "after update" event of the Location combo
me.SubLocation.requery
