How to generate a process when clicking on a button in Web Designer?

Hi there,

I have a button in the Web Designer and I would like to generate a process when clicking on it. What I would like to do, in particular, is to set some parameters of the process. Otherwise, it would be okay to populate the PC variable.

I know I can generate an event (link to another community post) when clicking on a button, but I think this is not what I need, because it doesn't let me set process' parameters or the PC variable. Am I wrong about it?

Any suggestion is appreciated.

Regards,

Francesco
