Live price update by select variants

[Sedaidruck]

Hello,

 

unfortunately, I have the following problem with my online shop:

 

the price in products don't update when I select variables or the amount of the product changes.

However, the correct price will appear in shopping cart.

 

Sample variables:

 

Ausführung: Glanz and Datencheck: Basis Datencheck = no update (basic price)

and

Ausführung: Glanz and Datencheck: Profi Datencheck = 15€ additional charge

 

Link to the product in the shop: http://www.sedaidruck.de/zickzackfalz-6-seiten-a4-200g/2421-zickzackfalz-6-seiten-din-lang-200g-2500-stk.html

 

Prestashop 1.6.1.0

 

How can I solve this?

 

Thanks in advance for your help
