problem with Asym example

[Shreyas Sarangan <sarangan@eng.usf.edu>]

Hi,
	I'm a newbie,... sorry if this seems too trivial.
 	I get the following output when I run 
(ns version 2.1b2)
~/ns-allinone/ns-2/tcl/ex/asym/asym-test-2.tcl :

ns: finish _o3 file3 file4 0 connGraphFlag 0: can't read "graphFlag":
variable is array
    while executing
"plotgraph $graph $graphFlag $midtime"
    (procedure "finish" line 8)
    invoked from within
"finish _o3 file3 file4 0 connGraphFlag 0"

Could some point out the correction required? All my validation test
suites run fine.

Thanks,
-Shreyas
