Call function from other script

What's the exact error it's giving you, and what's the code look like?

Um well depending on what method i tried it gives different methods

ive tried putting: var target : PlatformerController; on the killTimer script and then when it needs to be called i say :target.OnDeath(); but id does not work. it calls the function because it comes up with the debug message of "dead" but it does not call the Spawn() function inside the OnDeath() function

and if i call the Spawn() function from the killTimer script the same thing happens in enters the function but it does not reset the players position.

my reset player position script it :

function Spawn () { // reset the character's speed movement.verticalSpeed = 0.0; movement.speed = 0.0; transform.position = spawnPoint.position; // reset the character's position to the spawnPoint
}
