Is there a script that can concatenate and replace all columns D and E to column F and then move this into a new column D?
Thanks very much,
Robert.

EXAMPLE (Data in columns D and E could also be alpha-numeric, but will always be matched at the same comma points)

A..........B........C.............D.............E.................F.........
text....text....text.........1, 2.........3 , 4.............1(3), 2(4)
text....text....text.........1.............4..................1(4)
text....text....text.........1.............6..................1(6)
text....text....text.........1, 6.........7 , 4.............1(7), 6(4)
text....text....text.........1, 8.........9 , 4.............1(9), 8(4)
text....text....text.........1.............10................1(10)
text....text....text.........1, 10.......11 , 4...........1(11), 10(4)
text....text....text.........1, 12.......13 , 4...........1(13), 12(4)
text....text....text.........1.............14................1(14)
text....text....text.........1.............16................1(16)
