Dear all

I’m looking for a way to automatically add +1 to an x number for each run, but I need the number to be progressive. In other words, the first run should produce an x + 1 result, the second run should produce a result (x + 1) +1 and so on. This would allow me to automatically write in Excel spreadsheets the results of each run in different rows, without having to change the initial row manually each time i press run. I hope i was clear enough. Do you have any suggestion on how to do it? Thank you

Here’s a simplified scheme of what i’m trying to do. The issue is how to make the StartRow number increase automatically by +1 at each run.

You could need something as a Run Count:

I managed to solve it in this way, thanks to Read Excel plus ForceChildrensEval. It can be run with periodic run and it will allow me to leave it compute by night and then catch the results of the generations on the Excel spredsheet. Thank you for your suggestion Yna, i came to the solution through your answer.
