I have a custom object named Consultant that holds contact information for consultants of our company.  FirstName and LastName are the two fields within this custom object that represent the consultants name.  My issue, is that when running a lookup to this Consultant object, the record name is the value that comes up.  I can add fields to the lookup so you could see the FirstName and LastName but there is still a problem.  The object that is related to Consultant, will only show the record name in the lookup field in the record.  I want to make my record name for Consultant a formula field that is a concatenation of First Name and LastName.  The standard object Contact has a setup like this and I want to replicate it.  I don't see how to handle this if it's even possible.  Can this be done and if so, how?

Thanks,

Ralph
