I would customize the template Memberships - Receipt (on-line) in order to give a different message if it is a signup or a renewal. I try a lot of tokens, but no ones works: $receiptType $membership_status $membership_source $source $status $membershipStatus $form.receipt_text $formValues.receipt_text_signup $formValues.receipt_text_renewal $formValues.receipt_text $formValues.receipt_text.label $receipt_text $receipt_text.label
In the offline template I use $receiptType EQ 'membership signup'.
Have you any suggestions?
