I have a custom user field which I want to set based on a joomla group.
When someone registers on the site they go into 'group' Registered. When they become a members via Membership Pro they go into 'group' STHolder
In the custom field I want to set the value if 'group' = Registered. then custom field = Visitor or
if 'group' = STHolder then custom field = Season Ticket Holder
in the custom field there is ' Fill following parameter to get Options from DB table'
see screen shot
Can I use this to set the field value? If so do you know the table name and when and how can I set it.
