# AppleScript sum of a list

I'm trying to get the sum from a list.

The list newTotal:

{"30.00", "30.00"}

``````repeat with each from 1 to count of items of newTotal
set myFinalTotal to myFinalTotal + each
end repeat
``````

But the result is unexpected = 3

How should I do the math?

Modifying your original attempt:

``````set myList to {"30.00", "30.00"}
set myFinalTotal to 0

repeat with x in myList
set myFinalTotal to myFinalTotal + x
end repeat

myFinalTotal
``````

And for the joy of learning:

• Recursive:

``````to sumItems from L as list
if L = {} then return 0
(L's first item) + (sumItems from the rest of L)
end sumItems
``````
• Iterative:

``````to sumItems from L as list
tell (a reference to last item of {0})
repeat while L ≠ {}
set the contents to it + (L's first item)
set L to the rest of L
end repeat

return the contents
end tell
end sumItems
``````

Solved : I'm counting the list first then do my repeat statement

``````set sum to 0
set n to count newTotal

repeat with i from 1 to n
set sum to sum + (item i of newTotal)
end repeat

return sum
``````
