I am using a 'slider' block to control the value of a 'gain' block whose value is defined by a 'variable' set by the 'slider'. When I run the simulation, the 'gain' does not change according to the 'slider' value, what is going on?

    Gain block values in VisSim are only evaluated at the start of the simulation, so adjusting the “slider” during the simulation has no effect on the output value.
    See Below.

    To to dynamically update the “gain” value during simulation, use a “*” block like so:
