I need help with script!

[freakyone]

Hi
I just watched these Tutorials: http://www.youtube.com/playlist?list=PL6...ature=plcp
Now, I got a key to open a door and now I wanted to make another key spawn, after a Note is read, and when you take it an dead body appears (and should scare you) and you can open an Iron Maiden with the key.
Now Amnesia says:
"main (25,1): ERR : An function with the same name and parameters already exists.
main (102,1): ERR : An function with the same name and parameters already exists."

Can you halp me fix that?
This is my Script:



void OnEnter()
{
AddUseItemCallback("", "Key001", "Door001", "UsedKeyOnDoor", true);
AddUseItemCallback("", "Key002", "ironmaiden", "UsedKeyOnDoor", true);

AddEntityCollideCallback("Player", "ScriptArea_1", "TeleportingNakedGuy", true, 1);
AddEntityCollideCallback("Player", "ScriptArea_4", "TeleportingNakedGuy2", true, 1);
AddEntityCollideCallback("Player", "ScriptArea_5", "TeleportingNakedGuy3", true, 1);
