When hitting submit, I would like to trigger the download of a file (external URL) + display a message to the user + send an email to the user.

I also want to be able to set rules that the file is downloaded only if a certain choice is made in the form.

Is this possible?

Currently I only manage to either display a message or trigger the download and this case the browser stays with the form and doesn't change...

Thanks,

Karim
