AJAX for extra input fields

I have a form that asks users to fill in the quantity of an item they have sold. The form has about 20 products, each with a text input field to enter the quantity. I now find that I also need to capture each item's serial number.

I would like to design the form so that if the user enters 4 as the quanity purchased, four text input fields appear below the original, to accept the serial number information.

I need the AJAX to show the appropriate input fields for the serial numbers and to allow server side verification of the serial numbers as they are entered.

My current input variables are arrays: e.g. <input type='text' name='prod[PC900]' value='' size='6'>

I would prefer the serial number be a compound array. e.g. prod_serial[PC900][1], prod_serial[PC900][2].

I am already using some AJAX on the page using Rafael Dohms brilliant autocomplete script for the company field, and I have used some other AJAX code on my site (although not on this page), but they have been modifiations of published scripts. I am not a Java/AJAX guru myself.  

I am using PHP for the server side.

I really appreciate your help.

I tried to set this up, but I am having trouble getting xajax to work. I have installed it, and I can get the examples to work and as far as I can determine, I am setting it up according to the examples, but I keep getting an error "Fatal error: Call to undefined method xajax::processRequests()"

Can you give me the full xajax code to make this work?

Also my site is templaed, so I need to be able to load the variable $display with any displayed output or $head for any code that appears in the head of the document.

I will gladly award more points, or if you are available freelance, I can hire you to complete the code for me.

Dear hernst42:

As luck would have it, my clent changed their mind and no longer want this option.

I'll still try hacking through xajax, since it seems to be a very useful program.

Thank you for your solution.
