I'm building a website and need help with one page. This will require javascript programming skills that I don't have.

I have a code to submit values from child page to the parent page but some of the inputs I take values from are conditional or repeat - defined by php and the values are not transferred. Enclosed is the file with the code. The relevant pieces are the javascript code in the head and what is inside the "products" form.

The child page lists product details with supplier information. For each product there can be more than one supplier options: each option has one or two suppliers. This is stored in table ProductsJoinSuppliers where I have fields for the product_id, supplier_id and supplier2_id.
On top of this each supplier has contacts and this information also has to be transferred to the parent page.

At the moment only the following are transferred: (product)code and (product)name. supplier_id is transferred only when only one exists (when there's more it doesn't transfer).

This is what I'll expect you to do:
1. supplier_id, supplier_contact, supplier2_id and supplier2_contact must be transferred to parent page
2. when user selects supplier_id with the radio button, supplier2_id from the same table is selected as well
3. I will not give you any passwords for the server, for testing you'll need to use your own server

Please only bid if you know how to fix this (sample code and ideas of solutions are welcome so that I can check if you know what you're talking about and understand the project).
