I am unable to complete the assessment track with an error message:
Create the Restaurant Promotions custom field
I’ve revalidated that the custom field is present and added to Core.
Any suggestions/solutions are appreciated.
I took a look at your account, and it looks like the field was created correctly. The reason you weren’t passing the grading rule was due to the validation minimum and maximum - it was looking for a max of 3 items (which you had), but you also added a minimum of when 1 when our grading rules were checking for a minimum of 0.
I updated the field for you, so you can see that change in your account. Also, if you re-submit you should now pass the grading rules!
