Make pushbutton "1" when pressed?

[Yodoad]

I have some issues with pushbuttons.
I get a pushbutton with vdd pullups to work (0 when pressed)!
But how do i reverse this?

I have tried this solution but with no success:

loop:
  IF portb.5 = 1 THEN LED 
GOTO loop   

LED:
  high porta.2
  pause 100
  low porta.2
  pause 100
goto loop

And schematic in attachment!
