i seriously do not understand your question.

But from what I understood,

  1. you have one counter, xp → which values the hit points etc.
  2. Credit is added up for every kill.

if you want a counter for total credits and if you want that counter to be summed for every kill then,

var TotalCredit : int;

// Call this function whenever you want to add credits to it. 
//AddCredit();


// Function to add credits
function AddCredit ()
{
   TotalCredit++;
}

Credit = Credit + 1; is the way to increase it by one. BUT, the rest of it is way off. It probably shouldn’t be in Update; == won’t work (what if you go from 790 exp to 840?) and it needs a way to give each exp bonus only 1 time.

The thing is, adding one is such a basic thing that I’d recommend looking through some of the “How do I learn Programming” threads here.
