Referral Name

Sorry to keep bothering you.
I read… http://docs.itthinx.com/document/affiliates/shortcodes/referrer/
And tried it using… https://jacanawarranty.com/smartphone-splashpage/?affiliate=3
I added…
[referrer display=”name”] by itself…
and also inside.. [referrer display=”name”]
but nothing shows…
I was expecting for it to recognize the affiliates=3 parameter and show the referrer…

Ultimately when a tier affiliate sends a signup link ?affiliates=3 to the affiates registration page,
I would like it to say, you have been referred by…

Thanks in advance.
