I have a need for when deleting the formula within a cell, another
cell's value will appear as default. Following is a formula that
serves, and works well in a single, unmerged cell. However, it--not
anything else I have tried--works in a group of merged cells. Does
anyone have a suggestion, and even better, an adaption to this formula?

Private Sub Worksheet_Change(ByVal TargetCell As Range)

If Not Intersect(TargetCell, Range("L14:L14")) Is Nothing Then
If TargetCell = "" Then
TargetCell = "=Sheet1!O14"
End If
End If
End Sub

Thanks,
