[SOLVED] Ruby on Rails Enum ArgumentError

I was wondering if someone can see the obvious error I am making. I can't see it.

My Rails 7.2 application relies on an enum for :likelihood and :consequence. Unfortunately, in testing, I am getting an error.

I have followed this article exactly https://blog.saeloun.com/2021/02/26/rails-introduces-new-syntax-for-enum/ and can't see why i am getting the argumenterror.

I am sure I have made a simple error somewhere, but i just cant see it.

I have layed out the error, model, controller and form below. Let me know if you require more info.

thank you in advance
