Hello, would you like to help me to do Ultimate ordering form, easy for customer (because no one likes to register or fill 3-page forms). There is combo drop down + add input fields and extending form, for some reason it doesn't work properly, in Chrome add input doesn't work and in IE dropdown and add input doesn't work at all. you can check the code in Untitled Document

Combination of combo and input works fine in every browser Untitled Document

For the ultimate form we will need also total price calculation and some kind of bot protection(no captcha)
