Pose Script not working

[kieranfoy]

I'm working on a mod involving large quantities of spells, but one is giving me trouble. It's a little script supposed to make the player use the 'preach' animation for thirty seconds.

 

For some reason, though, it crashes my game when I've no weapon drawn, and does nothing when I do.

 

scn aapreachspell

 

begin scripteffectstart

 

player.additem aaapreachtoken 1

 

pickidle

 

end

 

begin scripteffectfinish

 

player.removeitem aaapreachtoken 1

 

end

 

Can anyone see anything deeply wrong with this?
