[ns] Error while running the tcl script while implementing a new protocol in ns2

[The Learner]

When I run my tcl script, I get the following error-

(_o14 cmd line 1)
    invoked from within
"_o14 cmd addr"
    invoked from within
"catch "$self cmd $args" ret"
    invoked from within
"if [catch "$self cmd $args" ret] {
set cls [$self info class]
global errorInfo
set savedInfo $errorInfo
error "error when calling class $cls: $args" $..."
    (procedure "_o14" line 2)
    (SplitObject unknown line 2)
    invoked from within
"_o14 addr"
    ("eval" body line 1)
    invoked from within
"eval $node addr $args"
    ("default" arm line 2)
    invoked from within
"switch -exact $routingAgent_ {

MSClusterHead {

}
MSDataDiscovery {

    (procedure "_o3" line 14)
    (Simulator create-wireless-node line 14)
    invoked from within
"_o3 create-wireless-node"
    ("eval" body line 1)
    invoked from within
"eval $self create-wireless-node $args"
    (procedure "_o3" line 23)
    (Simulator node line 23)
    invoked from within
"$ns node"
    ("for" body line 2)
    invoked from within
"for {set i 0} {$i < $val(nn) } {incr i} {
                set node_($i) [$ns node]
                $node_($i) random-motion 0              ;# disable random motion
        }"
    (file "simulation.tcl" line 60)

What does this error mean? And how can I rectify this?

Thanks and Regards,
