This is from the original thread:
Quote: "After reviewing the video and the script, I see the problem. The script will not work properly when there is more than one floor above the ladder. It uses the players proximity with the ceiling to tell it when to stop climbing. I will try to work around it, but for now it only works in a two story room. Likewise, a two story ladder will work in a three story room and so on. You can use a few invisible ceiling entities above the ladder to fix this issue.

Sorry, but that never made it in the Readme file of the download. Also, there have been some changes to the engine since then , but hopefully it will work properly still.
Best.
I'm sorry, my answers are limited. You must ask the right question.
