Combination variables don't update - error in cart

[Irene13]

 

 

Hi everyone, I have a problem with combinations.
I have three parameters to configure my product, the problem is that the variables don't update as they should.

For example, the "Red" type of pvc should only have a thickness of 2mm \ 200mm, instead all are displayed.

If I purposely select a combination that doesn't exist, the article is not placed in the cart and this error occurs.

 

 

I would need, as so far I have seen the combinations on Prestashop behave, that by selecting the type of pvc, the variables for the strip measurements were updated, removing those not available for colored pvc and returning available when there is actually a combination that includes them.

The calculator shown in the figure is part of a perfectly functional module, it updates the price exactly for each variable the problem seems to me to be in the prestashop mechanism itself.

Thanks a lot to anyone who will help me,

Have a nice day
