Activation link for new users

Hello,
​
We have created a form with chronoform v6 for the registration of new users in joomla but we did not understand how to send the activation link to the user.We tried to compose the link using the data contained in "activation_provider" but it does not work.
​
Can you help me please?

You can compose the link with

<a href = "{url:activation}&code={var:joomla_user#.activation}"> Click here to activate </a>

You'll need another event set up to handle the activation. I sell a demo form on my site, it includes an activation email and event.
