Hello everyone,
First of all, excuse me for my poor vocabulary.
I have a few questions for you :
1. I have a number of files library and a list. In each library I created some groups. they are the same but not the same (different files) . In the same way I created the same groups in the list. I would like to take the sum of each group from each of the libraries to the correct columns in the list.
I hope I made myself clear.
Is it even possible?

2. How can I build a graph that represents the list and it will automatically update and change itself within changes on the list?

3. I’m looking for html code to present the date that automatically would be updated every day.

Best regards,
