Where contains

Hi folks,

I am having a complete mind blank at the moment.

I have a multiple of products and within that I have a list which can have many values. I want to display  all the products that contain the value 3 for the following part:

Product Type (values): <?php echo join(', ', $record['quality:values']); ?>

  list($machineryRecords, $machineryMetaData) = getRecords(array(
    'tableName'   => 'machinery',
    'where'       => 'CONTAINS("$machineryRecords.quality:values", 3)',
    'perPage'     => '9',
    'loadUploads' => true,
    'allowSearch' => false,
  ));
