I have a simple query named: "Flow_Chart_1_Qry" that uses the followin tables
TABLES
1-Incident-tbl
2-Events-tbl
3_Conditions_tbl

Many fields in the query are check box field.

One of the check box fields in the 2-Events-tbl is:
 1-Human Engineering

I want to simply total the number of "TRUE" check boxes for the field:  1-Human Engineering
FlowChartOneTEST-DB.accdb

Where do I put this code? In the control source?

If you want to just sum the true values then, use this as the ControlSource in the group or report footer.

= Abs(Sum(TheCheckFieldName))

If you want separate sums for true and false, then you need two controls
The first one to count the true

= Sum(IIf(TheCheckFieldName = True, 0, 1))  ''''' this counts both false and null as false.

OR

= Sum(IIf(TheCheckFieldName = False, 1, 0)  '''' this counts only the false values

You can add it as a calculated field in your query.

It's mentioned in my Query Tips and Techniques paper: http://fmsinc.com/MicrosoftAccess/query/index.html#Functions
