ms access courses in london - Applyfilter problem

I have a query that simply looks at a yes/no field and if my continuous form shows it "ticked" it filters those records out. It also sorts by date at the same time.

I can run this as a form filter from the access menus easily enough by "loading from query" but here is the problem:

I have an option control with 2 choices on the form, one to run the filter query and one to reset it to all records.

Here is the line for "option 1"

DoCmd.ApplyFilter "qdfcurrmessages"

The fact that I am telling it use qdfcurrmessages seems to be ignored.
It just runs whatever the last filter that was used via the access menus.

A simple solution will let me sleep!

Thanks
