Hello respect NS-users, when I simulated followed this website: http://www.cse.msu.edu/~wangbo1/ns2/ (Bo Wang's website), But, I got the error messages since implemented $ns twoflows-1channel.tcl: invalid command name "if{0}{" while executing "if{[info exists channel2_]}{" (procedure "_o3" line 45) (Simulator node-config line 45) invoked from within "$ns_ node-config -channel $chan_6_ \ -channel2 $chan_1_ \ - -
please advice for me!!! Thank you so much in advance. Best regards, ByungJoon Oh,
