Im trying to make a quest where you have to pick up an item. Im doing the script for the item but something doesent seem quite right and I cant make it work.

Scriptname CrateScript2 extends ObjectReference
Quest Property EastEmpire01Climbingthecorporateladder Auto
Event OnContainerChanged(ObjectReference newContainer, ObjectReference oldContainer)
if (newContainer == Game.GetPlayer())
EastEmpire01Climbingthecoporateladder.SetObjectiveDisplayed(30)
EastEmpire01Climbingthecoporateladder.SetStage(30)
endif
EndEvent

I can just about manage to discern some typos in your script - EastEmpire01Climbingthecoporateladder is missing an 'r' - but seriously, if you want help, please don't use tiny lettering. There's a 'code' button you can use to put code in a different typeface,
