Script problem or Impulse problem?

[Your Computer]

Well I don't space them out and all my other functions work perfectly. Idk. :/

Are you positive that you have the item "letterkey"? If you don't have that item at the time of colliding with the area, you have lost your chance to get the desired result from the callback (given the fact that you are telling the script to remove the callback upon collision), therefore the second area, "biblescript," likewise won't activate.
