"operators" variable in set_operator_role_and_location is causing problems -- maybe remove and replace with if-then statement?

Because we are not setting it inside the function, it is remaining zero and is therefore returning this message even when [operator_details][ provider] == True: "Please specify exactly one operator role."

What if we get rid of this variable and instead just throw this message if [operator_details][ provider] == false
