Your array editor looks like it's saving the values as text instead of numbers. It shouldn't make much of a difference though as construct easily converts text into numbers.
However you will run into an issue when you try to add two array values together and they are both text. The text will be concentrated together instead of added numerically. The solution is to convert the values to integers with int().
Ex:
Array(1,2)="10"
Array(1,3)="11"
Set Text to Array(1,2) + Array(1,3)
// Text will be "1011"
Set Text to int(Array(1,2)) + int(Array(1,3))
// Text will be "21"
