Create T-Shirt & Hat order within Registration

I am using you Events Booking Component for a series of events around the country... we need the option for registrants to preorder tshirts and hats... I'm in the process of creating custom fields, but am a novice joomla user. In this case, I'm creating a radio list for users to select the tshirt size. Where I get stuck is what I am supposed to put into the Values, Default Values, Fee Values and Fee Formua fields. Any suggestions?

Hi

First of all, I am sorry for lack of documents for this . In this case, you will need to use custom fee field feature in the extension. This feature works much the same with the feature in my other extension called Payment Form. Please visit this link joomdonation.com/index.php?option=com_co...icle&id=70&Itemid=54 , look at the section How to use Fee Field feature in Payment Form to see how it works .

If you need more help from me, please let me know .

Thanks ,

Tuan
