# Mutually Exclusive Check box

• ### General discussion

• I'm writing a program for a class that requires us to use 3 check boxes but they need to be mutually exclusive. I am not sure on how to write the code so that they are mutually exclusive. Any help would be greatly appreciated.
```Sub ChkStandard_Click

FCControls.SetChecked(ChkPlatinum, "False")
FCControls.SetChecked(ChkGold, "False")
rate = .005

EndSub```

• Here is 3 mutually exclusive check boxes:

```checkbox[1] = FCControls.AddCheckBox("1")
FCControls.SetChecked(checkbox[1],"True")
FCControls.SetChecked(checkbox[2],"False")
FCControls.SetChecked(checkbox[2],"False")
FCControls.Move(checkbox[1],10,10)
FCControls.Move(checkbox[2],40,10)
FCControls.Move(checkbox[3],70,10)
For i = 1 to 3
FCControls.RegisterMouseUpEvent(checkbox[i],"Checked"+i)
EndFor
Sub Checked1
If FCControls.GetChecked(checkbox[1]) = "True" Then
For i = 2 To 3
FCControls.SetChecked(checkbox[i],"False")
EndFor
Else
For i = 2 To 3
FCControls.SetChecked(checkbox[i],"True")
EndFor
EndIf
EndSub
Sub Checked2
If FCControls.GetChecked(checkbox[2]) = "True" Then
For i = 1 To 3 Step 2
FCControls.SetChecked(checkbox[i],"False")
EndFor
Else
For i = 1 To 3 Step 2
FCControls.SetChecked(checkbox[i],"True")
EndFor
EndIf
EndSub
Sub Checked3
If FCControls.GetChecked(checkbox[3]) = "True" Then
For i = 1 To 2
FCControls.SetChecked(checkbox[i],"False")
EndFor
Else
For i = 1 To 2
FCControls.SetChecked(checkbox[i],"True")
EndFor
EndIf
EndSub```
