Hi Faraz

Can you please write the code in your email, because ns user mailing list drops 
all the attachments.

Hi all,

I get an error which I have enclosed when I try setting up nodes in wireless 
scenarios. I have tried a lot of different things as suggested by other 
tutorials but get the same error everytime. When I delete the lines defining 
the nodes from the code, there are no error messages. Code that I am using is 
also enclosed.

Please help me out at this, I really need help quickly.

Faraz
