title: Gather inserted text values from multiple rows in a report
body: <p>I'm currently struggling with Oracle Apex.
  I'm trying to create an application which enables customers to place their order. Therefore I create a report which lists the available products. Furthermore the report contains a column (the SQL query for that is simply <code>'0' as "Quantity"</code>) which displays a text box. In this text boy the customer should be able to insert the required quantity.</p>
  
  <p>I've create a screenshot to make it easier to follow me:
  <img src="https://i.stack.imgur.com/bczDe.png" alt="enter image description here"></p>
  
  <p>After the customer has fill out the form, the "Place Order" button will purchase the wished items then.</p>
  
  <p>My question is now, how is it possible to read out in which text boxes did the user filled in a number and also to which product belongs it!</p>
