you need to create the recordset to look up the options on the product detail page as:
name: reMetalOptions:
SELECT productoptions.OptionPriceincrement, productoptions.ProductOptionID, options.OptionName, options.OptionGroupID, optiongroups.OptionGroupName
FROM options INNER JOIN productoptions ON options.OptionID = productoptions.OptionID INNER JOIN optiongroups ON options.OptionGroupID = optiongroups.OptionGroupID
WHERE optiongroups.OptionGroupName = 'Metal' AND productoptions.ProductID = paramItem
then create the parameter paramItem using the run time variable:
$_GET['ProductID']
