If Not Intersect: Array Ranges

Hi,
I have this code:

Please Login or Register  to view this content.

Those ranges in lineArray are named ranges of a merged cell.
It works fine but it's annoying because even if I doubleclick anywhere else, it puts "+" to the left of the cell double clicked.

After googling, I think "If Not Intersect(Target, Range("___")) Is Nothing Then" is what I need to fix but I don't know how exactly with these ranges in array.

Could you help?
