Vary the resistor value while simulating the system?

I want to change the resistor value while simulation is run. I used Series RLC branch. I tried to do it using "set_param".

It shows

"Cannot change parameter 'Resistance (Ohms):

(Resistance)' of 'look_up_table/Series RLC Branch'

while simulation is running"

I used MATLAB 2019a version.

If Anyone knows the exact way kindly help me to do this.

Thanks

To vary the R/L/C parameters during simulation it is better to use variable Resistor/Capacitor/Inductor blocks. Both technologies in Simscape Electrical offer the variable Resistor/Capacitor/Inductor functionality which can be used to build an RLC branch.
