This issue is typically due to a setting within the Participant HQ of the event.  Participants have the ability to hide the amount they have raised, so Amount Raised or thermometer totals will show as Undefined instead of providing a dollar amount.

This setting can be changed by the participant by doing the following:

1. Log into the Participant HQ
2. Click Edit My Profile
3. Scroll down to the "Show Money Raised to Date on Personal/Team Page:" under Event Information and mark the checkbox
4. Click Update
