Use Reply-All to keep the thread on the list.

If the most recent WQN SIS Data Download table is 14June2018_WQN_Data_Download,
does it contain any data for the months July, August, September, October,
November, December? After extracting the data you create the file
"Anti-deg_requests/test.xlsx". Have you confirmed that all of the
dates you need are present in that file?

You need Santa Claus not r-help. You haven't given us a fraction of the
information we would need to help. You don't show us your code. You
don't tell us where the information is coming from except "today's
date." You don't tell us what data you want. You don't seem to know
