Switch until released myRIO / cRIO

Hi

I would like to control a stepper motor with buttons on the Front panel. They should have the function of switching until released.

But when I try to run the VI on myRIO or cRIO the attached error message occur.

Could anyone tell me how I can run those VI's on real hardware or how to cheat / create another way of getting the data of how long the button is pushed?

Thanks!
