@kowisoft it could look something like this. Collection the iterating values in a temporary file and appending that at each step of the loop. And then like you have already done collect the sum of the column and then make a decision to sop (or not). Maybe not the most elegant way…

Just make sure to reset the temporary file. One could also automate that by using a switch catching the first iteration of the loop (I have and example of that somewhere).
