Power Browse Form - Push button linked to hypercontrol problem.

I am using Demo 9.1. I have created a Power Browse Form with a reusable subform. I added a push button and labeled it Find as I want to replace the Find hypercontrol in the toolbar. In the Button Clicked event rule FC Find = HC F&ind. I get the following message....
A screenshot is attached.
