I keep getting an error on the following, where am I going wrong?

=IF(AND([status\_pr]=”approved”,[status\_sr]=”approved”,[status\_dr]=”approved”),“Submission Approved”,IF(AND([status\_pr]=”approved”,[status\_sr]=”approved”,[status\_dr]=”pending”), “Solution/Delivery Approved”,IF(AND([status\_pr]=”approved”,[status\_sr]=”pending”,[status\_dr]=”pending”),“Pursuit Approved”,”Pending”)))
