I am a new user of ADS and stuck in a problem for which I can't find a solution.

The problem is:

I have built a schematic circuit and then  form a symbol of it and use  that symbol in another schematic and use that schematic as another symbol to use it in the third schematic which is my top level circuit.

when I tried to simulate the top level circuit i got this error: 

*Error detected by hpeesofsim during netlist flattening.*

    *While evaluating expression `y1.X8.L2.L':*

        *expression has not been defined.*

I hope someone can guide me.
thank you
