Re: [ns] question about error in variable accessing via TCL

Hi Navid,
Thank you for your kind and quick reply.
But unfortunately I am still in the same problem.
Even I compiled successfully, nothing changed in error message.
..
Thanks anyway for your helps and I hope I could fix this problem soon.
If anybody has another suggestions, please let me share your ideas.
Thank you again
