I don't think you can directly put in your query like that into a grid because the output of a!queryProcessAnalytics is a PortalReportDatasubset. I would suggest putting your query outside of the grid in a local variable and then reference that local variable in your grid. That will also make it easier to debug, since you could see the value of that local variable and verify that it its correct.
