After a registrant signs up you may want to modify their submission. For example, you have a conference and provide the option for a registrant to choose which session to attend. That registrant might contact you and ask to switch sessions.
Select the registrant and then click the link “Edit Registration”. This will open a new window and will display the actual sign up form with the registrant selections. You can modify the selections by going through the registration process.
You cannot edit paid items that have a dollar value greater than zero.
