Hello Everyone, 

I am trying to make a new field with a formula, text data type, from a boarding pass. I have this but it's telling me Kosher does not exist. Any help appreciated. 

CASE(ISPICKVAL(Ticket__r.Food_Preference__c, Kosher, Kosher, Halal, Halal, Vegeterian, Vegeterian, Vegan, Vegan, null))
