Strange problem - negative quantity

[peter19]

When I add an item in my shopping cart, the quantity becomes negative. So it says quantity 1 before I add the product to the shopping cart, and -1 after adding the product. This messes up the calculations afterwards of course. I checked in the database and the database has the right quantity it seems, so where does this -1 come from?

 

Does anyone know a dirty trick to resolve this issue temporarily? It would be of great help.

Back up your shopping_cart.php by renaming it shopping_cartBAK.php.

Go download the plain osCommerce pages to your computer at: http://www.oscommerce.com/solutions/downloads

 

Then try uploading the plain vanilla osCommerce shopping_cart.php file to your server. Test.

If it still doesn't work, try the checkout pages in the osCommerce package.

 

Good luck.

I've tried all of that with no luck. You can view an example of the problem at www.e-kon.be/~bob

Click for example on "Anslot Cedric" or another name ; use access code "boboli", choose category "baby's kleertjes" -> you will see the right quantity, when you click buy now, the quantity becomes negative...

 

What is causing this?
