Interface SQL Filter on Group Name

Hi,

I am trying to filter an "Interfaces with High Percent Usage" on the group name.

In the SQL I am using the following syntax:

Station = '${Name}'

(Station is a custom property)

While I don't get an error, I am not seeing any results either so I enabled SQL profiler and found the ${Name} macro was not being replaced with the group name which it does on the graph's subtitle using Station: ${Name}

Any ideas, am I trying to do something not supported or is there a way to incorporate macros into the SQL?

Thanks,

Pete.
