@raymond1242 I have added a change refactoring some of the code. We still need to add this functionality to the clone modals.

Also, ensure that we verify both cases correctly when the name is present but the value isn't and vice-versa. I fixed it for the create modals because if I had an argument/env var name: it would raise an error but :value would create the job without verifying this is not a valid argument/env var.
