Hoping someone can offer me some assistance. I'm trying to execute a script and I keep getting this error message about "Error: element 12 is empty". I'm wondering if my syntax is incorrect within legend.list. If anyone has any suggestions to sees something obvious that I am missing, I would greatly appreciate any help.
