Reply To: Removing End of Line Underlines

That's odd. The script is written & tested for CS4, but it ought to work for CS3 as well. (You are not using an even older version, are you?)

Can you check if it actually creates a character style called “NoUnderline”? If there isn't one, it should make it automatically. (FYI, the variable 'blankStyle' should point to this character style, and should apply it in lline 31.)

It seems you didn't do anything wrong copying or running the script, as it would never have made it all the way to that line.
