Input field instead of pulldown

[swolock]

Is this the correct code to have an input field instead of pull down for quantity in slave listings?

 

echo TEXT_QUANTITY . '  ' . tep_draw_input_field('Qty_ProdId_' . $product_info['products_id'], '', 'size="4"');

 

If so, which file does it go in an what does it replace?

 

Thanks
