Filter Command Button

[Sol]

The wizard created the following code to filter a form
based on one linking field. I would like it to filter the
form based on (2) linked fields. The linked field below is
[Course Number], and I also need it filter by
[Semester/Year]. What do I need to add (and where) so it
will link both fields. Both fields are already in both
forms.

Thank you.
