Hello! Thank you for the response. I finally figured it out, sorry
for posting prematurely about it. But I think this may be a common
mistake people make, so I will explain what I did wrong here in the
hopes that it may be useful to others:
When I
created the text files for each station, I named them "tmpStation1",
"tmpStation2", "pcpStation1" etc. I thought that in both the pcp and tmp text
files, I could just list the stations as "Station1, Station2, etc",
thinking that the tmp or pcp prefixes were sufficient. I definitely
misinterpreted the format requirements of the sample files.
So, in the pcp and tmp text files, I listed the exact file name of each, and it worked fine.
Hopefully this was helpful and sorry to have posted before I fully finished troubleshooting.
