MS Access Form Filter

P: 4
Hi,

I've developed a form filter that produces a number of hours budgeted by employee/location/practice group/experience level and date available using some Allen Browne code. I have two command buttons, cmdFilter and cmdFilterAvail. cmdFilter filters the form based on the criteria selected via my list and text box filters. One of the fields in the form, text51 has a control source:=IIf([clientname]="Unassigned Time",[BudgetedHours],Null)

On click, cmdFilter filters my results but also shows the null values present in the data set where clientname <> "Unassigned Time". I'd like cmdFilterAvail to be able to keep the filters applied, but then narrow my data set to NON-NULL text51 values thereby showing only employees with available time.

Code for frmFilterAvail is identical to frmFilter and needs to have the NON-NULL piece added and I don't know how to do it...Help would be greatly appreciated.
