Help with disabling Checkboxes dependant on previous Checkbox

[McL4renF1]

Apologies for the basicness (if that's a word) of this query... but I'm a VBA virgin...

I have a spreadsheet that I've designed as a questionnaire to determine the level of complexity of a project - various questions are asked with the answers weighted to provide an overall score that determines the experience of the Project Manager required to deliver it.

The first set of checkboxes identify which strategic objectives of the organisation the project is linked to. The options are:

NONE
QUALITY & SAFETY
LEADERSHIP & CULTURE
CLINICAL STRATEGY
ACCESS & OPERATIONAL DELIVERY
FINANCIAL CONTROL

What I need is for if the "NONE" option is selected the other boxes can't be (until the "NONE" option is deselected). NB - more than one of the other options can be selected.

Can anyone help ?

Thanks (in anticipation).

Rightclick on checkbox1 (NONE)
Assign macro
New

Sub CheckBox1_Click()
If ActiveSheet.Shapes("Check Box 1").ControlFormat.Value = xlOn Then
    ActiveSheet.Shapes("Check Box 2").ControlFormat.Value = xlOff
    ActiveSheet.Shapes("Check Box 3").ControlFormat.Value = xlOff
End If
End Sub

For the other checkboxs:

Sub CheckBox2_Click()
If ActiveSheet.Shapes("Check Box 1").ControlFormat.Value = xlOn Then
    ActiveSheet.Shapes("Check Box 2").ControlFormat.Value = xlOff
End If
End Sub
