ADS 2011 co-simulation please help me

I'm trying to simulate a simple circuit. I start my design from layout,
then I'm trying to co-simulate with schematic and library model/symbol. I
get following message:

You shouldn't use schematic view to simulate your circuit because your structure has no schematic representation at all.
It's pure layout..Delete your schematic view otherwise ADS will confuse...
Then you have to simulate your EM model in a seperate schematic page.

Thank you .Regards

Thanks a lot. I had exactly the same problem, and I just followed your advice and its done.
