Hi
 After simulating jitter script I am getting following error,

ns: dump _o15 1: can't read "x": no such variable
    while executing
"expr $x+1"
    (procedure "dump" line 10)
    invoked from within
"dump _o15 1"

But in my script I include x in the following way,

for { set x 1} { $x <= 15} { incr x } {  	
		proc dump { link interval } {
		global ns integ
      		$ns at [expr [$ns now] + $interval] "dump $link $interval"
        	set delay(x) [expr 8*[$integ set sum_] / [[$link link] set
bandwidth_]]
    
         	set y [ expr $x+1]          
   		set jitter(x) [expr  delay(y) - delay(x)]
   		puts "[$ns now] jitter(x)=$jitter"
		   }
	}
	
	Would you please tell me what's wrong there. I will appreciate
that.
