In my query I have used [criteria] to stem a pop up dialog box for criteria. I would like to know if there is a way to add a drop down combo feild in that pop up so that you may choose your criteria from a list instead of using a cheat sheet to view all criteria available in that field? There are not enough charactures available to give ie. in the text area of the pop up.

Not sure I totally know what you mean, but you can accomplish a drop down by using another form (a pop-up form?) and place your combo box there. Then use

[Forms]![myPopUpFormName]![myComboName]

as your criteria in the query.
