I have enabled to the show the custom field to show in both individual and group registration with each member option checked. i see the custom field in the individual registration but i don't see it when doing group registration for each member. The custom field for group registration i see is the billing section, but i have check the each member option.
I think it was just a cache thing, i think i figured out the problem, but i am eagerly waiting for the new version, specially to looking forward for pay offline option, where user can choose offline payment and required fields pop up. something like if they want to bill to their account then when they select bill to account an input field show up asking them their account number.
Right now i using the additional information page to collect that information i hope i can use the offline payment section to collect that information.
