[ns] simulating error.....pls help..

[stan]

hi all,
   This is the second time i post this question. i
really hope somebody can help me.
   I tried to simulate a the example1.tcl in the
tutorial but i found an error like this:

Unexpected end of line in: + -t 4.49999999999999 -s 0
-d 1 -p cbr -e 5 -c 0 -i 8
0 -a 0 -x {0.0 1.0 80 ------- null}
Perhaps you are missing a value following the
attribute flag.
Last parsed attribute flag was -x

May i know why? how can i solve it? I always faced the
same problem like this while simulating other
simulation script. Is there any problem with my
installation ? 

Thanks and Regards,
  Stan.
