enable/disable checkbox by its resident cell location

I want to disable/enable a checkbox in an excel sheet using vba based on the value/conditon of another checkbox. I cannot use the checkbox name, I want to use it's cell location in reference to the cell location of the checkbox that is enabling/disabling it. something like this:

Sub Software2()

    Dim myRange As Range

    Set myRange = Range(ActiveSheet.Shapes(Application.Caller).TopLeftCell.Address)

    If ActiveSheet.Shapes(Application.Caller).ControlFormat.Value = 1 Then

        myRange.Interior.ColorIndex = 35
        myRange.Offset(0, 1).Interior.ColorIndex = 35
        myRange.Offset(0, 2).Interior.ColorIndex = 35
        myRange.Offset(1, 1).Interior.ColorIndex = 44
        myRange.Offset(1, 2).Interior.ColorIndex = 44
        myRange.Offset(2, 1).Interior.ColorIndex = 44
        myRange.Offset(2, 2).Interior.ColorIndex = 44
    Else

        myRange.Interior.ColorIndex = 44
        myRange.Offset(0, 1).Interior.ColorIndex = 44
        myRange.Offset(0, 2).Interior.ColorIndex = 44
        myRange.Offset(1, 1).Interior.ColorIndex = 0
        myRange.Offset(1, 2).Interior.ColorIndex = 0
        myRange.Offset(2, 1).Interior.ColorIndex = 0
        myRange.Offset(2, 2).Interior.ColorIndex = 0
        'ActiveSheet.Shapes(location of other checkbox).ControlFormat.Enabled = 0
        'ActiveSheet.Shapes(location of other checkbox).ControlFormat.Enabled = 0

    End If
End Sub
