Okay, so I am trying to make a SP map, and right now I am attempting to make a script to change to another BSP when I enter a Trigger Volume.

Here's the error i'm getting from Sapien when trying to compile the scripts:

11.13.08 16:17:54  recompiling scripts after scenarios were merged.

And here is the script I made to change BSPs

(scrpit startup bsp_change1
 (begin
  (sleep_until (volume_test_objects bsp1 (players)) 15)
  (switch_bsp 1)
)
)

I have the trigger volume set up and named "bsp1", and the script is named "bsp_change1."

If anyone could help me, it would be greatly appreciated.

If I remember correctly all you have to do is name the trigger volume is "bsp 0,1". Try it

So take out the script and try it then?

Yes.

Found your problem: You spelled "script" wrong.

It worked, thanks for your help Guru.
