I have a picklist field Accd__c on Case  with picklist values 15%,20%,50%,and Custom Object Codes__c with PCODES__c  field , and Percentage__c field  so whenever an user selects the percentage in Accd__c on case object I want the trigger to pull the number from Codes__c object and copy  it on  number__c field in Case record
