Accessing values from a repeater

Here's what I want to accomplish:

User enters teammate 1's name in a text field inside a repeater section.
User hits +Add to add another teammate.
User enters teammate 2's name in repeater text field.

On the last page of the form, I want to list the teams created.

How do I display:

Team 1
Teammate 1's Name

Team 2
Teammate 2's Name
(if the user didn't enter a 2nd team, this 'Team 2' section should not appear)

A description of how to access repeater data while still in the form (not in a view or an email) is hard to come by.
