Links in Repeater connected to Data Set

I’m trying to make a repeater on my site connected to a data set. I want each item in my repeater to have a link that says “Read More” but have each one go to a separate URL. If I try to add a “Rich Text” field to my data set, the formatting in my repeater gets messed up. If I try to directly add a link to the repeater, every item goes to the same URL. Help!
