[ns] Error in my script

[Tatiana Rotava Schabbach <tatianas@inf.ufrgs.br>]

Hello people,

I receive this message error when I try to execute simulator ns with my
script.

    (_o60 cmd line 1)
    invoked from within
"_o60 cmd attach _o58"
    invoked from within
"catch "$self cmd $args" ret"
    (procedure "_o60" line 2)
    (SplitObject unknown line 2)
    invoked from within
"$node attach $agent"
    (procedure "_o3" line 2)
    (Simulator attach-agent line 2)
    invoked from within
"$ns attach-agent $flow_vc($i) $udp($i)"
    (file "diss_1.tcl" line 150)

Someone have any idea what happened? Please, help me!!
If someone need more information about my script,  ask me, ok?

Thanks in advance,
