Pairs Game From Template

I have taken the Pairs template & am adding levels to it.
The 1st level has 16 tiles with 8 matches, so my score is 8 when I finish.
On my 2nd level I have the same number of tiles with the same number of matches.
So on each level I get 8 points.
I want it to accumulate points, thus I would get 16 points with the completion of the 2nd level.
Can someone point me how to accomplish this?

BTW…it took me awhile, but I figured out how to get rid of the screen where it says You Won & New Game.
I had to go to layers & choose the UI layer & then on the 1st level delete all the content on the UI layer.
I had already duplicated the 1st level to the 2nd level, so the 2nd level still had the UI intact.

Thanks.

Well, if each level brings 8 points, you can multiply the number of levels finished by 8 to get your score.
If levels bring different points, you can add the desired amount to your Score global variable when the level is finished.
You might want to take a look at the endless up runner and the Tetris demo example projects, both have scores.
