Thank you very much, it seems to be working. We will check it out as soon as possible. And in order for everything to be set up correctly, maybe you can tell me how to correctly take the Google Client ID (that is, not gclid, but cid, which is what _ga calls in cookies).
You can also specify in a separate hidden field what comes after the link sign with UTM or other parameters (that is, after the sign ?).
