    HankMcSpank, I spoke too quickly.... The pin used for the interrupt should have the cathodes of the two diodes connected to it with a pulldown ONLY... The other two anodes should be connected to each of the resistors and individually connected connected to the port pins to be read as well as the push buttons..
