Must Select

for osCommerce Online Merchant v2.2

If you have setup your products with a dummy default options such as 'please select', you typically still have the issue that the customers can forget to make a selection and add the product to the shopping cart with the 'please select' value selected. I've been sending people these instructions lately, but as the same question keeps popping up, I figured, better to put it in a contribution so that more people can enjoy it, and perhaps someone else can make better installation instructions and improve the whole contribution. This is a pretty easy install, just a few files to edit, but not yet an easy straightforward install. The check for the missing attribute is done in the application top, based on the identifier for the 'must select' option values id used.
