Thank you so much.


You won't be able to write text to an id field.  Can you explain why you want to write a descriptive text field to a lookup?


Hi Bob

Email_Description__c I use a Field Test!


My needs is the Field SuppliedName from Web-to-Case put in Field Contact. WhenCase was created by a web-to-case, it will auto poppulate SuppliedName to Contact.


Thank you so much
