Reply To: GREP help please…! index page numbers to increase by two.

Increased by 2 what? 2 points or do add onto 52 so it's now 54?

GREP can't do maths by changing numbers from 52 to 54 and 55 to 57, 56 to 58, it just can't do it.

It could if you give an example of the text (a good chunk) to find the Numbers of pages and increase it by 2points in size, or 2 points in leading.

But no – it won't be able to +2 onto every page number. A script might be able to – but I don't know how.
