reset my variables to 0

There is code pertinent to debugging missing.

Line 29 & 30 is where I am trying to reset line 7 & 14 after that particular condition is met ... why isn't line 29 & 30 resetting 7&14 to 0 ?

just before your test (the if, not the else if of course!) put this alert :
 
alert("Player1 :" + Player1 + "\nPlayer2 :" + Player2 + "\nPlayer1SetScore :" + Player1SetScore + "\nPlayer2SetScore :" + Player2SetScore + "\nPW :" + PW);

I did all of that. And it resets. The variable there but when I click the button again. It. Continues from 4...5...6..7... etc

Line 26, 27 you're creating local variable, not using the global
so remove the var keyword

I tried this code  and it did not work

}else if (Player2 > 3 && Player1 <=2)
		{ScoreSelf.text ="lost";
		ScoreOpp.text= "game";
		PW = 0 ;
		PointsWonII = 0;

Select allOpen in new window

I said remove the var keyword
You removed the full lines...
let :

		Player1=0;
		Player2=0;

Select allOpen in new window

I did that because I realized I didn't need those resetting and where left over from an earlier attempt ... I need PW = 0; && PointsWonII=0;

so how do you it stop looping/increase/decrease?
you just remove the only lines able to stop your increase/decrease, say nothing about that, so where are we going now?

>:o(

Here is the whole section... if you push the PointWonBtn (Button) then PointsWonII increases.. and Points Lost Button PW increases ...once the score reaches 4 for one or the other I need it to start  the score over hence PW = 0 and PointsWonII = 0;

var PW =0;
var PointsWonII =0;

// Create UI i this area


//Logic area 
PointWonBtn.addEventListener("click", function(e){
	Ti.API.info('Pw=: ' + PW);
	PW =PW;
	PointsWonII = PointsWonII + 1;
		
	PointsWinner( PW, PointsWonII );
});

;

is there another way to handle it because it's a tennis scoring so sometime in certain condition the score can equal 5 or 6

Do it work for 4? It was your previous request...

does not work... keep counting on from 4

And this one ?

var PointsWinner = function(PW, PointsWonII){
       if( (PW+1) == 4 ) {
             PW = 0;
             PointsWonII = 0;
             return;
       } 

Select allOpen in new window

Thanks you got me thinking in a new direction... I incremented in the function

var PointsWinner = function(PW, PointsWonII){
       if( ((PW+1) >= 4) && (PW - PointsWonII)>=2  ) {
             PW = 0;
             PointsWonII = 0;
             return;
       }
