Alain - Thanks for your suggestion. I tried it and got different results. Still getting good servo response to the pot, but it does not seem to be registering the min and max values when the buttons are pressed. The servo continues to move to the full limits.

Just to be clear, the SetLimitSw is a slide switch. When it is slid to the On position, the program will monitor for the pressing of either the min or max pushbuttons (momentary). When the SetLimitSw is slid to Off, the program will apply the limits that were set.

The concept is so simple (at least should be) that I am embarassed that I can't get this to work - I have done projects that are a hundred times more complex than this. I know the answer is staring me in the face - I just can't see it!

I appreciate all the comments and encourage more!
