Please help if anyone aware of this. $ ./nsns: [code omitted beacuse of length]: invalid command name "Agent/GPSR" while executing"Agent/GPSR instproc init args {$self next $args}" I will be highly gratefull to you. Thanking u, Regards, Nikhil _________________________________________________________________ See how Windows Mobile brings your life together—at home, work, or on the go. http://clk.atdmt.com/MRT/go/msnnkwxp1020093182mrt/direct/01/
