I refer to this circuit for short circuit and short circuit alarm to do multisim simulation. The function is to control the sound alarm on the right with the switch on the left.
But it's too bad, I don't know why it can't run, the prompt is a simulation error. (Probably there is a problem with the relay, this is indeed beyond my knowledge) Does anyone help me see where the connection is wrong? How should it be modified? Thank you very much!

There is a problem with the circuit, the diode.

The wrong component is selected, the relay and the switch must be corresponding and can be found, do not use other alternatives, otherwise, the circuit is not the original circuit, and the DC power is not connected.
At the same time, the shortcut keys of the keys must be modified to different keyboard key values, don't all be keys = A.
The polarity of 12V is reversed, and the others are not looked carefully, it is probably almost.
