Macro problem..

[APN]

I am using the following macro...

ActiveSheet.Unprotect Password:="1234"
'Sub InsertRowIF>3()
If Selection.Rows.Count > 1 Then Exit Sub
ActiveSheet.Protect DrawingObjects:=True, Contents:=True, Scenarios:=True, Password:="1234"
If ActiveCell.Row < 4 Then Exit Sub
ActiveSheet.Protect DrawingObjects:=True, Contents:=True, Scenarios:=True, Password:="1234"
ActiveSheet.Unprotect Password:="1234"
ActiveCell.EntireRow.Insert
ActiveSheet.Protect DrawingObjects:=True, Contents:=True, Scenarios:=True, Password:="1234"

End Sub

The problem is I have a rows A & B blank C with TOTALS .D..E..F £.....

A..Blank..B..Blank..C..TOTALS..D..amount $..E..amount $..F..amount $..

I would like to know how to include in the above macro.....to end sub if the row with the above info on it is selected for a row insert....i.e. I do not want a row inserted on selection of row with TOTALS on it as it affects the formulas..

Any help much appreciated....
