Turning Checkboxes into Numeric Values

Excel 2007 - VBA Coding
I have a userform that when the submit button is clicked dumps the data collected in the form onto a spreadsheet. Currently the checkboxes dump a "True/False" statement onto the spreadsheet. Userform has 24 checkboxes. I am wondering where/if I can have the "True/False" produce either a 1,0,-1 (number) based on the selection, rather then the "True/False." There are eight series of three checkboxes. Each series has a Yes-Checkbox, a No-Checkbox, a N/A checkbox. I'm thinking a Yes=1, No=-1, N/A=-1 from the overall count. (As in the question does not count as it doesn't apply.) The overall score is based on eight questions, or however many apply. (See attachment1 for Userform, this attachment also includes the VBA coding for the submit button on the userform) :banghead:

Something like this?

Code:

---

Range("A4").Select
Do
    If IsEmpty(ActiveCell) = False Then
        ActiveCell.Offset(1, 0).Select
    End If
Loop Until IsEmpty(ActiveCell) = True
ActiveCell.Value = cboNames.Value
    ActiveCell.Offset(0, 5) = IIf(CheckBox1.Value, 1, IIf(CheckBox2.Value, 0, IIf(CheckBox3.Value, -1, "")))
    ActiveCell.Offset(0, 6) = IIf(CheckBox4.Value, 1, IIf(CheckBox5.Value, 0, IIf(CheckBox6.Value, -1, "")))
    ActiveCell.Offset(0, 7) = IIf(CheckBox7.Value, 1, IIf(CheckBox8.Value, 0, IIf(CheckBox9.Value, -1, "")))
    ActiveCell.Offset(0, 8) = IIf(CheckBox10.Value, 1, IIf(CheckBox11.Value, 0, IIf(CheckBox12.Value, -1, "")))
    ActiveCell.Offset(0, 9) = IIf(CheckBox13.Value, 1, IIf(CheckBox14.Value, 0, IIf(CheckBox15.Value, -1, "")))
    ActiveCell.Offset(0, 10) = IIf(CheckBox16.Value, 1, IIf(CheckBox17.Value, 0, IIf(CheckBox18.Value, -1, "")))
    ActiveCell.Offset(0, 11) = IIf(CheckBox19.Value, 1, IIf(CheckBox20.Value, 0, IIf(CheckBox21.Value, -1, "")))
    ActiveCell.Offset(2, 5) = txtComments.Value
    ActiveCell.Offset(0, 1) = DTPicker1.Value
    ActiveCell.Offset(0, 3) = cboCoaches.Value

I imagine the three checkboxes for each question are mutually exclusive? If so, do you have code behind them to ensure this? If not, may I suggest either you use option buttons which can easily be made mutually exclusive without code, or to use a single togglebutton, which can have three states corresponding to your n/a,yes/no. This last would mean you only have to look at as many controls as there are questions to get a score.
I've started a bit of exploration of this but need to see some feedback to be sure I'm not on the wrong track.

Exactly what I am looking for. Thank you XLD

Thank you for the suggestions p45cal. I think I'm goin to roll with XLD above reply. Thanks for looking at the situation.
