Output is giving an indexing error when I try to use table.concat(), why?

I was trying to print a table (I ran it using F8 and the script was in the workspace), so I ran the script and I got this error: 12:45:59.933 - Workspace.Script:71: invalid value (userdata) at index 1 in table for 'concat' This was line 71: print(table.concat(exampleTable, ", "))
