New to matomom hard time tracking users

I am looking for an Analytics tool and Mamtomo looks exactly what I am looking for, I was trying to assign SiteId but strangely it doesn’t work for me and I was wondering whats is wrong


Have you already check the HTML source to see if the echo works correctly. Also check you browsers developer tools for errors.

When I did echo, I can see the user email in the variable but the value doesn’t pass into matomo
