SOLVED Forcing a page to refresh... or ?

[Nicolas Flam]

Hello

I need some technical advice.
I have a landing page in which I have a validation button for a product.

I'd like to be able to add a second product.
It's not a shopping cart system.

I've thought of two approaches:
1-Forcing a page refresh after adding the second product (on which I know how to keep track) and if so, how?
2-Using your shopping cart system doesn't seem appropriate for presentation reasons: it's essentially a sales page with a salesperson on the phone with the customer. But I confess I'm not familiar with it.
3-A different approach? Suggestions are welcome.

@nicolas-flam you should use javascript to do that
You will probably need a developer to help you
