Changing Subreport filter in VBA

Question

I have a form "PriceListPrint" that has a field named "CategoryID" and command button to open a report "PriceListEnglish". In the form before the open report command
there is this line: CategoryID="Rest"
In the report there is a subreport "PriceListBeef" that has 2 fields "CategoryIDRest" and 
"CategoryIDRest2" I only want to show one or the other, not both, if I manually go into the subreport "PriceListBeef" in the Filter Property and write in either of the controls it works, When I tried to do it in code on the
"On Load" of the subreport:
If Forms![PriceListPrint]![CategoryID]="Rest"
then
Me.Filter="CategoryIDRest='Rest'"
Me.FilterOn=True
Else
Me.Filter="CategoryIDRest2='Rest2'"
Me.FilterOn=True
End If
It gives this error "The setting you set isn't valid
for this property"
If I click on “Debug” this line is highlighted in yellow:
Me.Filter="CategoryIDRest='Rest'"
I am working with Access 2002

Ken,
Thank you for your time.
Sorry I forgot to say that "PriceListRestaurantEnglish" report is only a holder for 7 subreports,
the names of the subreports are as follows:
"PriceListRestaurantBeef", "PriceListRestaurantDeli", "PriceListRestaurantPork", 
"PriceListRestaurantPoultry", "PriceListRestaurantSea", "PriceListRestaurantGoat","PriceListRestaurantFruit"
