I have a table which collects the referral source. It has the following fields
Last name, first name, school, etc.
What I want to do is create a Full Name Calculation which I know is simple but what I want this one to do is give me the Last Name, First Name but if this is blank give me the school name. Just not sure how to properly write it out. I'm sure it's quite simple as well i just don't fully understand all the proper ways of writing calculations yet.
