Hey higgins, how are things going. Haven't seen you around for awhile. Of course, I haven't been around very much lately.
Yup, the semi-colon shouldn't be there if you want the line to work. FPI EditPad will consider this correct because it is correct -- of course only if you were wanting to comment the line out.
Addendum:
However, the syntax is still wrong. First I'm not sure where you are getting the command
jumpoff.
Here is how the syntax should be for this.
;Artificial Intelligence Script
;Header
desc = Jumping off
;Triggers
:state=0,plrwithinzone=100:jumpoff=1
;End of Script
However, you will get an error saying that jumpoff is an invalid command. Unless you are using a mod that has this command. If you are using a mod that has this command then you are going to have to add all the new commands so that they will be accepted by the autocheck.
