RB0 interrupt and toggle issue

[mister_e]

Well it has to go to the ISR, but probably you want to refresh the Payload value with the PushButton?

In this case...

keys2: ; Called by Interrupt update relay

        pause 20 ' small debounce delay
        if !PORTB.0 then GetOut ' button up?
                                ' If so, getout of here... no need for noise call

        PayLoad = PORTD ' read PushButtons and update Payload Value
UpdatePort:

You could also use a timer interrupt and poll PORTD, this will allow you to remove all those diodes, and leave RB0 for something else. As it is user push-button, you'll probably never feel the latency of the Timer interrupt.
