Thank you Aleks. Unfortunately this is not exactly what I need. I would like to have, on "My Page 1", 3 buttons: "product 1", "product 2" and "Product 3". When I click on one of them, the presentation of this product appears on the same page in a dedicated box. When I click on another product button, the description of this other product should appear in the same dedicated box.
is this what you need?
look at following example here.......
Basically yes, the functionnalities should be the same. Instead of previous and next, I need the name of all my products on a column. How do you do that?
take a look one more time at this here.....
That could be your solution.
