Unrecognized member 'Health' in class 'UTPlayerController'

i am a beginner programmer learning Unrealscript I was wondering if anyone could help me with this error code:

Unrecognized member 'Health' in class 'UTPlayerController'.

The error that I'm getting happens on this line in the code: RandomController.Health = MaxHealth;

Below is a link with the code that i'm working on :)
