Hi all
I created a flow when a response item is submited to update a sharepoint list.

The form has 3 paths.
New project: add status, % completion, date of completion.
Status update: add status, % completion, and the project ID
New target for completion date: add the project ID and new target for completion date



The flow is here detailed:

The problem I have with the flow is that it adds items but it does not modify existing items on the sharepoint list. For example if you select the option status update or new target for completion date, if you enter the existing project ID on the sharepoint list and fill the rest of the data, the sharepoint list wont update, it will add a new item
So the question is, how to update an existing item in sharepoint list when I want to give an status update or enter a new target date.
Regards.
