I tried to create an invoice for my shopping cart. I select the the item from the db as drop-down list and if I click the item it gives me the price automatically. That's on the first input select option. Then when I loop the input select option form for the rest item, (i.e) item 2,3,4 and so on . It didn't display the price. The first item displayed due to the id I used in my jquery. Please am new here and I need your help. Thanks. My code below

What I have tried:

HTML
<form method="post" id="invoice_form">
        <div class="table-responsive">
