the file .tcl is (dccp.tcl)

Q1 : when i try to simultate this file a wrong message was showen :

num_nodes is set 2
BWA Type: 2
INITIALIZE THE LIST xListHead
la station de base est créée
channel.cc:sendUp - Calc highestAntennaZ_ and distCST_
highestAntennaZ_ = 1.5, distCST_ = 550.0
SORTING LISTS ...DONE!

Lines 157 - 158 in "dccp__lwx-LTE__nassou19891.tcl" :
$ns at 1.0 "$ftp($i) start"
$ns at 600.0 "$ftp($i) stop"

What is ($i) ? I.e. ($i) is not defined :

$ ns_WimaxLWX+lte+dccp dccp__lwx-LTE__nassou19891.tcl
can't read "i": no such variable
while executing
"$ns at 1.0 "$ftp($i) start""
(file "dccp__lwx-LTE__nassou19891.tcl" line ..)

P.S. : dccp.txt, dccp.tcl, dccp.tcl.txt are generic names.
Please new unique names for files. Preferably a descriptive naming.
