Hi again Bill, so I am trying to understand the code here. What this code is trying to do is to obtain a url that would download all the Excel files that belong to the date range I state as first_date and last_date?

When I run the code, all it downloads is a 0bytes document "d64e048c-d12e-4a8a-b9b1-500cf3141117.tmp"
Any explanation why this is happening?
