php mysql can't multiply a mysql result and a variable - php

Question

I can't for the life of me figure out why i keep coming up with 0 on this ... i'm pulling a price from one of my tables and multiplying it by the quantity they are putting in in the form ... for some reason it when i try and do the math, it keeps coming up as 0 ... any help?
code:
$get_code = "SELECT * FROM products WHERE p_code LIKE '%$po_code%'";
$run_code = mysqli_query($con, $get_code);
$row_code = mysqli_fetch_array($run_code);
$count = $_POST['ord_amt'];
$price = $row_code['p_price'];
$sum_total = $price * $count;
form code:
<form action="" method="post">
<?php
include('includes/connection.php');
global $con;
$cust = "SELECT * FROM users WHERE u_id = '".$_SESSION['u_id']."'";
$r_cs = mysqli_query($con, $cust);
$rw_c = mysqli_fetch_array($r_cs);
echo "<input type='hidden' name='c_id' value='".$rw_c['c_id']."'>";
?>
