I am trying to make 3 different combo boxes function as filters for my form. The data from each of them comes from a different table and those tables are used as the row sources. All the other data on the form is from a fourth table but the fields that the combo boxes use from their tables are in this table as well. The record source for the table is all the fields from the table and the fields that the combo boxes are using with their criteria set as the combo box selection. In addition I have the event for each of the combo boxes set to after update and have Me.Requery as the code. If I have a single combo box in use it works to filter but if I try to have more than one as a field in the record source with Me.Requery set for them as well I get an enter parameter value pop up. Does anyone know how I can use Multiple Combo Boxes to filter my form? I want it to function as an "AND" not an "OR" btw.
