osCommerce v2.3 online shop needs to modify Attributes.
I've already installed Add-Ons: Must Select v1.2.
I've set the default option which is - Please select -.
The error message should appear if the user hasn't make a selection and adds the product to the shopping cart, however nothing happens and the user can check out.
All data and sql/php will be provided from the sample site
