I haven't done anything to 'lock' the formatting. The macro does have:
Code:
With .Range.Font
.Size = 8
If ContentControl.Title = "Select Date" Then .Italic = True
End With
which ensures they stay at the 8pt size and that the date control remains in italics. The preferred way of controlling font attributes, as I said previously, is through the use of Styles, in which case, those lines wouldn't be needed.
