[ns] Class error-any suggestions?

[Shaili Desai]

Hello all

I tried to run the above attached script in NS and got the following error.
I saw on the forum, people had such errors before also,but there were no
solutions suggested for the same.

Can anyone help me with this, I am not getting a way out!
I would appreciate if you can help/
Thanks in advance.
