Mandatory checkboxes

Hello everybody,
I would like to have the terms of service and privacy conditions accepted before participating in an interactive video.
I would like the two checkboxes to be mandatory.
Can you advise me how to do it?

I am not able.

What library should I use?

Thank you

Moin buci on Mon,
In your case, it would probably be most clever if you were to insert a simple html page on which the conditions must be fulfilled so that a redirection to your video page takes place at all. Sorry but you have to solve the Javascript stuff yourself. I can't understand your conditions. Maybe you can explain that?
