for {set i 0} {$i < $num_nodes} {incr i} {
    set a($i) [new Agent/MessagePassing/Flooding]
    $n($i) attach  $a($i) $MESSAGE_PORT
    $a($i) set messages_seen {}
}
set Consumer n(0)
set Producer n(5)
$ns attach $a(1) $consumer
$ns attach $n(5) $producer
$ns connect $consumer $producer

where a comes from the agent node.Please tell me anyone why this gives error in agent a(0) in this line:

$ns attach $a(1) $consumer

What is `num_nodes` set to? – Donal Fellows Feb 13 '17 at 14:10
You are mixing the capitalization of Consumer/consumer and Producer/producer. Tcl variable names are case sensitive. – glenn jackman Feb 13 '17 at 16:13
@DonalFellows num_nodes are total number of nodes wich is equal to 6 – Jeckkie chain Feb 14 '17 at 08:32
@glennjackman sorry, here we capitalized the words otherwise in code we have used the small letters Please tell me the solution Thanks – Jeckkie chain Feb 14 '17 at 08:32

Including the actual error message would probably be useful here. – Erik Johnson Feb 14 '17 at 20:30
