generating report from combo boxes that have 'all' selected

[guinb]

i have a form with 2 boxes for start date and end date as well as 2 combo boxes for serial number and aircraft type. if i select a specific value for each then the rerport is generated just fine but if i select 'all' in the combo box for serial number then the report will come back with nothing in it. where should i start to look for the problem at?

Are you filtering the report based on the value selected in the combo box? How? You are going to have to give us more information about how the report is "generated" .

In your code.

Specifically in the code that calls the report, and any preceeding code that sets up the filtering.

If you want more specific help, then you need to think about actually asking for it more sensibly.
