I am trying to combine data from multiple pivot tables (looking at ozone pollution averages across each month and several years) for multiple air monitors. I'm running into several errors, one of which is the 'source denied' error message. I was able to successfully merge the data into one pivot table for one monitor, and following the same proceedure am not able to do so for another monitor.
The error I'm getting is "An exception occurred: [DataSource.Error] Access to the path '/Users/myusername/Desktop/Channelview2017.xlsx' is denied. (Session ID: 23b4d5d2-e355-482c-89c6-16366e284290)"
