MULTIPLEXING 1 7-segment display w/ 2 switches using PIC16F84A help?

the condition is

Switch 1 = on
Switch 2 = off
the display counts down from 0-7

however when
Switch 1 = off
Switch 2 = on
the display counts down from 7-0

and when both switches are on or off
there is no display

any delay for each digit will do as long as it can be seen...

any help with the program and the circuit? i would forever be grateful, tnx!:smile:

submit a copy of the code and your current circuit to be helpful in any way
