I assume this is Simulink? If so please add it to the Products list in future. It does save people time to not open questions they know nothing about!

A red line implies, that there is no connection between the two blocks. Simscape blocks from the Foundation Libary and the SimPowerSystems are not connectable. Try the RLC-Block in the SimPowerSystems/Simscape Components/Passive Devices libary instead of the resistors etc. from the Foundation libary.
