You have an event registration form in NetCommunity. You may have multiple events added to the same form or possibly multiple event price options within the event. You want to have more than one fund for the form. Perhaps you have two events within the same form and you want one event to have one fund and the other event to have a different fund.
Only one Fund per Event Registration Form part is allowed. If multiple funds are needed, multiple event registration form parts will need to be created and then added to unique pages.
