TOPIC: Can't remove cost from an event that is free!

Hi, I mistakingly created an event with a $25 cost that should have been free. When going back to remove the cost under DTRegister Event edit, it will not save that change. What am I doing wrong?

Thanks in advance.

Never mind... I got it. Instead of leaving the cost fields blank to save the event, I realized it probably needed a number (0 of course) to save correctly.

When I did that, it worked perfectly.
