First of all thanks for a great contribution!
I've tried my best to find the answer to the problem I am having as I know it's very frustrating when people as questions and the answer is easily available somewhere. However I couldn't find a solution to the problem I am having.
I've installed STS and Oscommerce v2.2 RC2. It works well for the "normal pages". I tried to create a template for the products. An example of the problem can be seen at http://japsports.ie/catalog/product_info.php?products_id=16. I wanted to remove the $content and instead create my own formatting using some of the variables such as $productname, $regularprice etc.
The problem I have encountered is that instead of outputting the values in the above variables it prints out the variable names (see the bottom of the link above, left the $content in the template, just to show that it works, but the other variables don't). Another strange thing I've found is that even if I remove STS or disable the use of STS in the admin panel, the product template is still used.
The snippet of code that displays the content on the page is:
<div id="maincol" >
<h3> $productname </h3>
<br> $regularprice </br>
Any help would be very much appreciated.
