What you want is a Union Query. If you have two or more tables with matching field names, you can set the rowsource of a combo box to a Union Query String. Following is an example from one of my apps...
SELECT id_string & ID, id_string FROM tblRequest UNION SELECT id_string & ID, id_string FROM tblExcursion UNION SELECT id_string & ID, id_string FROM tblRandD UNION SELECT id_string & ID, id_string FROM tblUnrelated ORDER BY id_string;
Hope this helps...
