Whats wrong with my code?

Hi guys

Trying to get this to work. What I want it to do is take the number value from 'Number Received' and add the record that many times:

                // Before record added
function BeforeAdd(&$values, &$message, $inline)
{

      
$count = $values["Number Received"];

    for($i = 1; $i < $count; $i++)
    {
        $query = "INSERT INTO Stock
        (`Hospital`,`Manufacturer`,`Department`,`Item Type`,`Batch/Lot Number`,`Expiry Date`,`Number Received`,`Received...
