I was refering to my button command. Should I start the port high and pull it low or start low and pull high based on this bit of code?

Code:
delay = 0
    Button Temp_Up, 0, 255, 0, delay, 0, Up_Loop
    button Temp_Down, 0, 255, 0, delay, 0, Down_Loop
Up_Loop:
    If Temp_Up = 0 Then
        Setpoint = Setpoint + 1
        lcdout $fe, 1, "Setpoint = ", Setpoint
        Pause 1000
    Else
        Goto Start_Convert
    Endif
    Goto Up_Loop
Down_Loop:                
    If Temp_Down = 0 Then
        Setpoint = Setpoint - 1
        lcdout $fe, 1, "Setpoint = ", Setpoint
        Pause 1000
    Else
        Goto Start_Convert
    Endif
    Goto Down_Loop
