Script begginer, My first script... Options

[egm]

Here what I want: make a container invisible for everybody unless a thief (or a character with the detect traps skill) detect a special trap. Detecting invisible container should reward XP. I have a container named "Cont01" and a trap "Traps01". i decided to code that in the area script (AREATEST)

Here it is:

IF
  True()
THEN
  RESPONSE #100
ContainerEnable("Cont01",0)
END

IF
  Detected("Traps01")
THEN
  RESPONSE #100
RemoveTraps("Traps01")
ContainerEnable("Cont01",1)
DisplayStringHead("Cont01",XXXXX)//You have detected a secret container!
AddexperienceParty(YYY)
DisplayString((),ZZZZZ)//You win YYY XP
END

Is it correct?

By, the way, it seems that the trigger Detected () isn't triggered by the spell effect: find traps. I mean, when its Yoshimo with its class ability, it works, but when it's Jaheira with a spell, it doesn't.
