i'm having little problem here, i have got timer here that counts down from a set time, but what i want to do now is instead of having timer, i just want to make a counter so if(counter=10) stop the game, and not when time = 0

You mean like declare a global in the JavaScript and increment on each choice or set to zero at the beginning of a new game instance?

var counter = 0;

function incCounter() {
   counter++;
   if( counter > 9 ) {
     alert("Game over, dude.");
     counter = 0;
     // restart game or something
   }
}

what i want is person starts a game, no times is on.. after he presses start button a equation is given (random) as he answers it(right/wrong) it counts this entry, and another question is given and so on until 10 questions have been answered

Well, this version gives you 10 guesses...not sure what to do at that point though. I call ResetGame() in the incCounter function (line 130)...
Search through the code for "counter" and you see the additions I put in.
