2-page form, displaying on 2nd page, want to skip empty fields

  1. Greetings,
    I'm trying to do exactly what this post title suggests.
    Here's my test page: http://goo.gl/8zV8c
    Page 1 of my form will have 125 products to choose from, each with a quantity field.
    Page 2, the html field should display only values that the user has entered on Page 1 along with the product title and price.
    I've messed around with the foreach loop that builds the html content as outlined in the third code snippet here:
    http://www.gravityhelp.com/documentation/page/Gform_pre_render

    //this is a complex fieldset (name, adress, etc.) - get individual field info
    					foreach($field["inputs"] as $input){
    						//get name of individual field, replace period with underscore when pulling from post
    						$input_name = "input_" . str_replace(".","_",$input["id"]);
    						$value = rgpost($input_name);
    						$html_content .= "<li>" . $value . " value: " . $input_name . "</li>";
    					}

    But I don't know how to check to see if the user has entered a quantity for a specific product field or not.
    Any help is greatly appreciated.
