Totalling check boxes

[springschick]

I need to total check boxes. That I know how to do. My problem lies here.
What I need to summarize are the boxes that are not checked. I have used
=IIf([Load Safe]=0,1,0), where Load Safe is my checkbox. This changes the
values in my check box so I can count the checkboxes that were not checked.
My problem is counting them. The text box I used for my formula is called
Load Safe Checkbox. If I use =ABS(sum([Load Safe Checkbox])), when I run my
report, it asks for a parameter to be entered into Load Safe Checkbox. It is
not counting the number "1" . I need some assistance in tallying these
inverted checkboxes. Thank you.

Put a hidden textbox on the report...name it txtNoCheck. Set its RunningSum
property to "Over All". Set its ControlSource property to
=IIf([Load Safe]=0,1,0)

Then put a textbox in the Report_Footer section of the report (this textbox
will show the sum). Name it txtNoCheckSum. Set its ControlSource property to
=[txtNoCheck]

Thank you for the response. I did exactly this, and the total comes out as
"1". It is not adding. Anything else I should try?

In which section of the report did you put the new txtNoCheck textbox? It
needs to be in the same section as the checkbox control. And be sure that
you set the Running Sum property to Over All, as I noted.

My mistake - I forgot to move it! It works beautifully. Thank you so much for
your help!

You could use the following expression in the summary textbox. There is no
reason to do the conversion at all in Load Safe Checkbox unless you want to
display that value in the detail line.

= Abs(Sum([Load Safe]=0))

or this alternative expression.

= Count(IIF([Load Safe] = 0,1,Null))
