-- url of the page with the problem -- : scarvesaustralia.com.au
-- HikaShop version -- : 2.6.2
-- Joomla version -- : 3.5.1
-- PHP version -- : 5.6
-- Browser(s) name and version -- : Safari

I do not seem to be able to change a setting in the configuration for the product related item display. Here is a screenshot:

When I click on the link to "access the display option" I am referred to a module id that does not exist (module id 158).

When I try to select a new module, I get the following screen and I do not know how I could possibly assign another module id 102.



What do I miss here?

Thank you

I feel I have done this before ... hmm, yes it works now, thank you Nicolas
