Question : Need expression that will total all yes checkbox responses on Access 2003 Report

Have a report called PeriodReport created from query of tblHistory. Two fields, FormInaccurate and FormIncomplete.  I need to total yes responses for each and then determine percentage of yes responses on each.

Among others,
I have tried =Count("[FormIncomplete] = -1") and =Count([tblHistory],"[FormIncomplete] =True")
I am not a programmer. Just trying to use Access for a simple report.  Can you help me?

Answer : Need expression that will total all yes checkbox responses on Access 2003 Report

Something like that:

Private Sub Form_Load()
    If DCount("*", "NameOfYourProjectTable") = 0 Then
        Me.NameOfTheSetupButton.Enabled = False
        Me.NameOfTheLogOutButton.Enabled = False
        ' ...and so on
    Else
        Me.NameOfTheButton.Enabled = True
        Me.NameOfTheLogOutButton.Enabled = True
        ' ...and so on
    End If
End Sub
