While the query may be in use for a form, as far as Access is concerned,
your report is using a completely different query.

The easiest approach would be to create a form with unbound controls to
accept the four parameters. Have your query refer to those form controls
rather than using named parameters (i.e.: rather than [Beginning Date] as
the parameter, use Forms![NameOfForm]![NameOfControl]). As long as the
parameter form is open when your form and/or report is open, you won't be
prompted.
