momentary setting a digital tag

I am trying to create a button that will set a digital tag to 1 momentarily then change it back to zero. Tried putting %Tag%=1 in the mouse down field and %Tag%=0 in the mouse up field, but that did not work.

Any help is appreciated.

There was previously discussion about it here as part of this question.

It's true that Pulse is not the most bulletproof method to guarantee that both parts of the toggle will occur, but in reality I've used it numerous times in ControlLogix and CompactLogix systems with Citect SCADA with very little problem. I can't explain why it's not working for Charles here because it definitely should.
