Multiple Checkboxes: VBA Select All/None

I have several checkboxes in a form and the program will run different macros depending on what the user chooses. There are 9 checkboxes total. 1 checkbox activates all other checkboxes while the other eight are the options. If a user clicks the All checkbox, the other 8 are activated. If All is unchecked, the other 8 are unchecked. The trick is that I want the All checkbox to change to False if any of the 8 options are triggered to False. The problem I am having with the code I have is that if I trigger any of the options to False, the chkAll macro kicks in and turns all of the checkboxes to False, not just chkAll. Somehow, I've tried using the Change and the Click event with chkAll but it seems to be behaving the same using one or the other. I have pasted the code below as well as included an attachment of the file with the form.

Private Sub chkAcq_Click()
If chkAcq.Value = False Then
chkAll.Value = False
End If
End Sub

Private Sub chkAdmin_Click()
If chkAdmin.Value = False Then
chkAll.Value = False
End If
End Sub.........................
