Products variable [solved]

[janvl]

Where is $single_option set?

If I leave the SKU empty, Cart2 cannot funktion.
If I try to put the same SKU in an option as in the product, I get an error 2 x the same SKU is forbidden.

On
http://neu.karin-schmuck.net/index.php?page=mode-tst
the variables are shown, $single_option is empty in all products.

It seems necessary to set it in order to use options.

BTW only product Mode01 has 3 options set.

edit - solution
I used smarty to set it myself.

Kind regards,
Jan
