Combination generator autoselecting value

[singhdeepakrana]

Hi

i am trying to implement the prestashop at the following link

 

http://northerntools...ller=product#/-

 

i have used the combination generator to generate the 2 type of drills for this particular product and by default it selects the 110 volt.

but sometimes after selecting 240 and you want to re select 110 it wont allow you to reselect 110 and will auto select 240.

 

On the following page

http://northerntools...ller=product#/-

 

i added 230 after 240 and now i cant select 240 and it automatically selects 230.

Could you please help me to handle this issue..

does the problem lie in how i am creating the combinations?

 

i have noticed that when i visit the homepage and then visit the product page then this problem does not exist but if i visit the product page via sub category then i cant select any combination

 

 

Please suggest

Your help will be much appreciated.

Regards
