Error: expecting (

I have no idea what is wrong. I am calling a function just as I have at least a dozen times my various scripts in this game, but for some reason it doesn't want to work now. Here's my script:

function PerformSet()
{
  //a bunch of code

  AddItUp();
}

function AddItUp()
{
  //a bunch of code
}

And the error is this: BCE0044: expecting (, found 'AddItUp'.

It doesn't even have a problem with the PerformSet function. Am I just doing something stupid?

Can you post the 'bunch of code' because it sounds like the first bunch has a problem.
