Hello Louise,

The [] in Rails acts as a reader while the []= as a setter. It appears like the problem you are getting is occurring on line 10 that is at multiauth_url(provider). You will therefore need to check it or use a compiler to fix that error.

It also looks like that provider is nil in this case, and there what you will need to do is try using pry (a gem) and after that you will drop in binding.pry to debug the issue further. In the event that you are assuming that  a provider already exists, just check to make sure that the provider is not nil first.

Hope this helps.

Regards,

Carl
