Changing Hard Coded Column References To Variable References

I have a number of statements within the Sheet Event Code (Excel 2007). Three times lately I have added a column and had to go back into the code and find all of the references that needed changing to reflect the new column.

I have been working on this for a couple of days and even tried EE, but to no success.

I have read that Defined Names / Constants should be used as often as possible, but even trying that, the VBA code errors out or "hangs up". Even within Bill Jalen's book (VBA and Macros 2007), there is nothing that addresses this, especially using Intersect.


Private Sub Worksheet_Change(ByVal Target As Range)
Dim rng As Range

On Error GoTo mEnd
Set rng = Sheets("Log").[F14:F10000]
If Not Intersect(rng, Target) Is Nothing Then
If Target = "" Then
With Sheets("Log")
