Final Version, thanks to Kenny with the Python 🙂

Output = []

for sheet, revision in zip(sheets, revisions):
    revnum = []
    for rev in revision:
        r = Autodesk.Revit.DB.ViewSheet.GetRevisionNumberOnSheet(sheet, rev.Id) 
        revnum.append(r)        
    Output.append(revnum)
        
OUT = Output

```

Edit: Just a couple of other thoughts…

I’ve added a bit to the beginning of the graph to Clear all the Issue values. Otherwise if someone’s put something in where it should be blank, that would remain.

You’ll likely want a way of recording the sending out of drawings at the same issue. E.G. you send tender drawings to the client, then a week later you’re asked to send the same drawings at the same revision to a contractor. Perhaps you could use the ‘Issued to’ revision parameter to log those and Dynamo could read them somehow?
