Q. Why is this showing before the person clicks "Process Registration? Total amount $20.00(including $20.00 extra fee).
A. In this case, go to Event Booking -> Translation, find the language item EB_TOTAL_AMOUNT_INCLUDE_FEE . Right now, It is set to%s(including %s extra fee). Just change it to %s (remove the including extra fee text) and It will work like you want !
