SCR Creation in Component Wizard

For a design that I am currently working on, I wanted to use SCR's that were both rated higher, and not obsolete. I've tried using the wizard to emulate a TN5050H-12WY (data sheet linked) but after all the data is input, the end result never seems to function.

To remedy the fact, I tried looking at the base code for the MCR716T4G, and change it to match the values from the STM SCR. Again, no luck. Multisim didn't want to recognize the code.

I'm attaching both the created SCR, as well as the edited code.

Any help or guidance on where to look next to solve the problem is much appreciated.

I've been using this circuit to test.

Have you tried with AC power source or more voltage? I tried higher voltages 1000V+ and the led turned on, also with AC. Maybe there is some parameter messed up.
