The requirement is like ECom Finance Advisor profile user do not have permission to close the cases and still if he trying to close the case, it should give error. For this i have written a validation rule like below, but it is not working.

AND(Owner:User.Profile.Name="ECom Finance Advisor", 
ECom_Quick_Close__c == true)

ECom_Quick_Close__c is checkbox type field and ECom Finance Advisor is name of the profile.
