how can we add numbers?

[stephen perry]

Hello, I'm getting the lines of rows from LIST1 and putting it to a variable 1
now I do the same with LIST2 and put it to variable 2

how can I do

variable 1 + variable 2 = numbers? I need to check this to see if all LIST are done

thank you

you can either use "variable operations", then "increase var value by" and put another var there, or use a JS or C# own code block and sum it there

thank you, I used C# code, cuz when I used increase var value + another variable, it gives me error
