Hi Nigel,
In design view, click on your checkbox, press F4 to bring up the
properties, then select the "Event Tab". In the AfterUpdate propert
select "Event Procedure" then Click the "..." button next to it. The
VBA Editor will open up. Paste the following code between the Private
Sub... and End Sub lines:
If Me.yourCheckBoxName.Value = True Then
Me.Detail.BackColor = 14742526
Else: Me.Detail.BackColor = 1776523
End If
Replace yourCheckBoxName with the name of your check box. (Can be found
in the line Private Sub yourCheckBoxName_AfterUpdate() line)
The numbers there are the colors. To get the numbers for the colours
you want, click on the form background and choose the two colours you
want one at a time and note down the numbers access assign to that
colour.
Hope this helps,
David
