On D7 I have set up a new panel page variant and want to use it with a certain selection rule:
String: URL path Current path is "*/cars/*?buy"
Eg I want this panel variant to be used if the URL is
However the above doesn't work. Adding
?buy to the url doesnt trigger it to be used.
Would anyone know a way to set selection rule so that I can use this page variant with a give parameter in the URL?
