Parameter Sweep AC mangnitude


I have a circuit as attached. I'm trying to do a sweep on the magnitude of my AC source (V1) at 100kHz frequency. The goal is to plot the transfer function V_out/V_source in magnitude and seeing it become nonlinear as I increase the magnitude of the AC source

I went to analysis and simulation >> Parameter Sweep and set up the circuit as below: 




When I click run, it says "There are no valid output variables". Any help is appreciated!

I am not sure if it is related with this, but when you open the A_Power on the value tab, there is values that needs to be set in order to make the AC anaylisis, you can try changing those.

Attach voltage probes at input and output of your circuit. Under "parameter sweep" analysis, In "output" tab add expression "V(PR2)/V(PR1)".
