agilent genesys question

Lets say I have a 12 port in genesys. When I go to plot reflection coefficient of a port higher than "9", what do I type into the "graph properties" box for a smith chart. For example, if I want to see the reflection coefficient of port 11, what do I type? If I type S1111 I get and error message. If I type S11,11 I get another error message.

I'm no expert in genesys but did you try to right click on the port 11 and select New Graph S[11,11]
You could also try typing S[11,11] into graph properties.
