I have set up DTR for client and they are taking group registrations using the ''member discount' option sent to 'amount'. My understanding of group registrations is this -- if you are logged in as a member the entire group will be given the member discount
In reality the client often has members registering for an event where there are both members and non-members, and need to charge both the member rate and non-member rate depending on the attendees status
The client does not have 'group discount' rates -- just individual rates -- however wants the convenience of allowing one person to register both members and non-members.
I recommended to client that they do not use the Member discount feature which automatically calcualates the discount -- but rather custom button which will allow you to choose price for each individual.
Is my assumption correct that custom button is the best approach -- and indeed will allow you to choose pricing status for each member?
Correct... in this case you'd need a custom field selection for each member to choose their member status, then their rate can be calculated appropriately.
