[ns] still unable to configure mobile nodes; prob with node-config statement

[Hari Prassadh]

this is my complete code. i ve basically taken it from the in-built
examples. even the examples in the directory ns-tutorial dont work
properly. could u please help me out by spotting the errors as i am
totally new to linux and ns-2 and am doin a project in ns-2. it keeps
returning error in the statement "$ns_ node-config -adhocRouting
$val(rp) \"
