is v21 a user defined variable, or was it all ready set by agi studio?
v21 isn't used by AGI Studio.

None of the variable are used by AGI Studio.

They are used by the AGI Interpreter

And yes v21 is used by the AGI interpreter it determines the ammount of time the text window should stay open(for a dialog box) then closes it after the time in v21 is up.
Kon-tiki, make sure that you got my latest code, I modified it yesterday when I noticed that I used reset instead of set on f15. And yes it does work... although I only tried it in NAGI since AGI doesn't work in XP.
