Two techniques:
1) Base the query on a parameter query and pass the value of the combo box:
Forms!<formName>!<cboName>
where <formName> is the form containing the combobox, and <cboName> is the
name of the combobox control.
2) Set the filter of the form based on the value of the combobox (same
syntax).
