Add all the ints from a list and give me score.

In very simple words what I want to do is, add all the ints which are in a list and give me a total of that as score.
Note : I am an artist just trying to code my game so, whatever you tell me be sure to explain it.
debug.log = "Thanks"

 

Here are some steps you need to do:

- create a total variable and set it to zero

- iterate the collection (list? array?) and sum each value into the total variable

That should give you enough to google on.
