Help with Field allignment in a report

[Imgsolutions]

So I created this report that is a bill for my company's customers. I have a place for the field FirstName, LastName, Degree, Address, etc. I would like to have the a comma between the last name and degree, but mainly I would like to have the fields autofill to each of there true lengths and have the next field follow after a space.
For example I want this: James Blake, MD, 1577 dkjfdk drive


Not: James Blake MD 1577
Thanks for any responses.

create one report field and in the ControlSource property concatenate your fields from the recordsource. Ex.:

=Trim(FirstName & " " & LastName & ", " & iif(isnull(Degree),"", Degree & ", ") & Address)

Thanks so much for the reply, I entered that in my control source property and it did try to insert them, but my filed names are actually First Name and Last Name, with a space in between. What should I do then. And how should I create this field? By adding the menu bar option saying Add Existing Field, or how should I do it?

Create a text box on the report. In the control source property of the text box, put

=Trim([First Name] & " " & [Last Name] & ", " & iif(isnull(Degree),"", Degree & ", ") & Address)
