[Discuss-gnuradio] Fw: Re: Error in executing filtering example

Thanks for reply.
Actually from the presentation I could get all values but for ¨variable block¨ with ID as taps , i was not sure what value I should choose as it was not clear from the presentation i downloaded. I guess if proper value is given to that block, the flow graph will run.

Hi all,
I was simulating filtering.grc example from Digital Modulation Primer using GNU Radio by Tom Rondeau. However during execution it gives following error. Can anybody help it out.
