Hello everybody,
I’m using 3 Single Selection Widget and a Variable to Table Row node to append a table. For the moment, each time I refresh my workflow, only one line remains in the table but i’m looking for a solution to add a new line to my table each time i press the refresh button.
The solution is surely with loops but I wasn’t able to fine anything working yet.
Thanks you
Can you post your current workflow? That would make it easier to get help.

Your workflow only has two widgets rather than the three you described. Do you to want to keep adding rows on a refresh or simply have three rows with the values refreshed? Also, why do you need three widgets rather than just one?
I’m not sure this is what your after. Its a little clunky. To start fresh delete the Data.xlsx file from the data folder in the workflow. Then manually set the initial values in each of the widgets. Run the workflow and then the updates are automated.
It’s working, thank you wery much. I didn’t think about the excel writer/reader.
