PSIM LISN simulation error msg

I was performing simulation for single phase PWM inverter; to measure the CM and DM noise, I have added a LISN ckt as above, however the above error msg is coming. I have used separate gnd for PE and signal gnd for analog measurements.

what is the issue with the simulation?

    Dear User,

    Is the subcircuit "S10" the SignalAnalyzer block? I am also noticing a few GlobalVariable block definitions. Are you trying to implement a state machine or conditional statements?

    BR,

    Hi Nikos,
    I am trying to simulate the Common mode noise spectrum for a single phase PWM inverter. I think the global variable declaration is irrelevant to my query.

    Could anyone help me out to find the error in the Simulation?
    I modified the simulation file.

    Now, some other error is coming as below.

    Here, the s14 is the Ground Plane Block.
