Hello, thanks firstly for a great program! I'm trying to create an equation which provides the rms value of a waveform. The equation is: Vs_rms = rms(Vsource.Vt) where Vsource.Vt is the sinusoidal source voltage (transient analysis). I can graph Vsource.Vt, however I end up with the following error when I attempt to simulate the circuit with the equation, and the equation result will not graph. Output:  Starting new simulation on Wed 12.
