Link the Sign Up Button to Another Page

Hello guys, how are you?
Since I’m new to the coding universe I need help for an event that I want to achieve.

I made a custom sign up form for my site. However in the Sign Up Button there is no option for link a URL. So I thought i can use code with Velo to make this happen.
As you can see in the screenshot below there is no an option for link.

I tried to use the function but nothing happens

So… How can I make this work?

Thank You,
