[ns] can't read "ragent_": no such variable

[Luís Barreto]

Hi,

I'm using DSR routing protocol in a wired-cum-wireless simulation and
am having the following problem:
can't read "ragent_": no such variable
while executing
"subst $[subst $var"

Could you please tell how to set up this variable and solve this
problem?

I got this problem for a long time and couldn't solve it. I´ve
searched and no one says the solution

Thanks for your help.
