Apologies for not being clear.

I was asked to update this index and noticed inconsistencies in the format of ranges eg. 128-0 & 128-30 and was trying to find the simplest way (for me) to deal with them, obviously 2 digits numbers after the dash is best.
Really just need to increment all the page numbers by 2, hope that makes more sense.
Thanks for any help

p.s.
Just realized another misunderstanding, the previous post I sent you highlighted in red the errors that were output from the script you sent and where not meant to indicate results that I expected - sorry for the confusion.
