Need help with Adding new field / button

Hi all

Please help I need to find a way to add a new "button" as it is on this link:

sidewinderadventures.co.za/bookings/inde...event_id=97&Itemid=1

If you see there are two buttons called WIIVoucher and CityMob I need to now add a new button for a new "voucher" and I havent the faintest idea where to look first to do this.

I am a noob at this component but need to have this done asap.

any help is GREATLY appreciated. If you click on these buttons you will see it leads to a "Group booking form and a Individual booking form"
The same must apply for this button.any idea on where to look first?

THANK YOU

You can look at the file components/com_eventbooking/views/event/tmpl/default.php to see the code of the two buttons. (Please note this is not original version of Event Booking, it seems the developer on your site has customized it) .
