Setting up multiple choices for product packages

Hi,

I am doing a switch from agora to zencart, for a bilingual babygear store. In agora, I set up some packages, where customers can choose the colors of up to 12 diapers, and enter them into the pack. Agora is like this:

http://littlewonders.com.tw/store/agora.cgi?cart_id=1384011.5096*z98b37&product=MT_Package&ppinc=package

In zencart, I have set the packages up to this point:
http://native-tongues.info/wip/littlewonders/index.php?main_page=product_info&cPath=65_135_152&products_id=196

I have added all the colors into the attributes section, so you can see them on the drop-down bar when you choose individual diapers:
http://native-tongues.info/wip/littlewonders/index.php?main_page=product_info&cPath=65_135_137&products_id=225

I have been searching but can't work out how to let customers choose one pack, and choose all the different colors or other options. I noticed other stores using zencart don't have this option like I had in agora cart. Is ths because you can't do it? Or am I missing something simple?

(I am using 1.3.8a and had someone help me set up the site, English and Chinese, so have added some language packs. I also bought the help book e-start your website but can't find the answer in there, either.)

Any help appreciated!
