Resolved SelectedPerson Property not found

[simsenVejle]

The result should be; When click on a firstname in the combobox it should display the lastname in a textblock.

When running the code I get an error : SelectedPerson Property not found on object of type ShellViewModel. I have checked it about 50 times. I have a property in PersonModel with the name LastName. Im not sure but I think is it possible I have to use another character than underscore?

I'm starting to learn about Caliburn.

My view (ShellView)
