Script Problem!

[Dwail]

Hi, guys!. I'm with another problem!

I'm trying to make an script for listen, when i push Toggle Battle Stations direct access, with Ui interface menu of TheDarkWright, the sound correct for each case. (on/off)

I'm created the next script file, /data/scripts/AI/Crew/Toggle_battle_stations.aix :

strategy Toggle_battle_stations(wp)
{
action
{
Wp:ExecuteCommand( "Toggle_battle_stations" );

if Wp:Isbattlestations() then
{
Wp:PlaySoundWithLipsync("ExecutiveOfficer\Normal\M C_CR_SO_01_A", 0)
}
else
{
Wp:PlaySoundWithLipsync("ExecutiveOfficer\Normal\M C_CR_SO_03", 0)
}
endif;
Wp:ScriptCompleted();
}
}

When I active this script the game cause me CTD, when I try to loading a mission. I don't understand what's wrong!. Please, can you help me?

Thanks in advance!.
