exec.library always v40?

[rvo_nl]

Another thread from me, sorry. I just keep having issues and questions. Now that I finally have my harddrive and OS3.9 installation sorted, I wanted to modify this little script:
 
http://deliriumbbs.freehostia.com/Dualbooting_AmigaOS_4_and_AmigaOS_3.9.bbs
 
so that it allows me to select which OS to boot from (I now have 3)
 
however, no matter in what OS I try (okay, Ive only tried wb3.1 and os3.9) I always get version 40.x of exec.library, so the version check fails to work.
 
any idea why? something wrong with the syntax perhaps? can I check for something else that is made resident by the rom updates of either 3.9 or 4.0?
 
have a good night, all. and thanks for your answers.

yeah thats what I did. I didnt get round to installing boing bag 1+2 this time, though it did cross my mind this could be the cause.
 
thanks, will continue next year
