Strange coding bug

I cannot seem to find the problem in my code. I have two pages. Both need to select a product from a database. The first page works fine, the product is found and I use the data in the page. The second one does not fetch the product. The code is exactly the same: $query="SELECT * FROM products WHERE stock_number = '$item_number'"; $result=mysql_query($query); $row=mysql_fetch_array($result); When I do 'echo $result;' on the first page, I get the result number. But if I do it on the second page I get nothing. Both pages are connected to the database and I get no errors in code. I have included the full code of each page in the attachment. Item_details.php3 is the working page and addtocart.php3 is the one that won't seem to connect. Thanks, Patrick
