Oh no, I just noticed I get this message on the live site, when I try to put that item in the cart:
Warning: Cannot modify header information - headers already sent by (output started at /var/www/html/www.segufixshop.eu/web/detailTest1.php:350) in /var/www/html/www.segufixshop.eu/web/detailTest1.php on line 386

Maybe I started this all wrong. I tried to have both version and size with nothing preselected. So I added in the table tblPrice an item with "-" for version and size at a price of $0.00. With this I achieved to have no version or size preselected, but instead of forwarding to the cart page, it adds the item in the cart but stays on the detail page with the ugly warning.

This warning did not show up when I tested locally, and it also does not show up for other items. Just item 13, for which I added the $0.00 item line to the data base.

If this goes beyond the help you can give me here, please let me know. I will wait a little while, but then delete the $0.00 lines from the live data base.
