get value of the second cell when using onRowSelect?

Suite and Optimus Suite 5
#1

the userid is the second column in my row. How can I get the value so I can pass it to my load?

registration_grid.attachEvent(“onRowSelect”, function(rID,cInd){
var uid = ???
nametags_grid.clearAll();
nametags_grid.load("./php/nametags.php?uid="+uid);
cell_nametags_grid.showToolbar();
});

this seems to work…

var uid = registration_grid.cells(rID,1).getValue();
