[U.S.I.G.1]

Hello. I have searched this forum, other forums and the internet hi and low for hours on end, read tutorial after tutorial, tried practicing time after time to no avail. Finally I end up here.

I have a question, and I would like an answer. Sorry, I don't mean to be rude, I just want a clear answer, not people yelling and flaming me because I don't know what I am doing.

I want to create a ladder on Southern France going up the north wall of the building by the gate at coordinates ( 752.85 -979.22 16.13 ). I want the ladder to go from the ground all the way up to the top of the roof. I have tried to make a ladder in MOHRadiant but the map will not compile ( it gives me a WARNING message that it cannot find a brush or something and the compiler stops running.) Now, I have found a post with a script to edit a ladder on a map, but I do not understand it. I am asking, is there a script for making a ladder on Southern France at the specifiied coordinates, and can someone give it to me? Thank you.
