Cannot open csv file

Why is it that I can load one csv file but not the other? They are both in the {PATH} directory:

please provide output of !ls {PATH} -l


copy/paste !ls {PATH} -l command from my question , you enter 1 instead of l


oh i see…the permissions

execute !sudo chown -P 644 {PATH}/* and try to run your code

This worked: !chmod 644 {PATH}/*

I am very grateful for your help! Thank you so much!
