I need to calculate the average from this list. everything works, but the variable is overwriting and I have to turn the applications off and on for the calculations to be correct. What can I do with this? [20211222_223611]

I have to turn off and turn on the Application for the result to be correct. every time i use the “average” function everything is x2 and so e…

here all the blocks. the function works, but the computations overlap each time I want to use it. If that’s not possible, how else can I build such a function? [20211223_123859]
