the parallel programmer

i was trying to follow the instructions here as good as i could. but i didn't have a 220 ohm resistor and substituted it for a 220 K ohm resistor, which i would imagine changes the behavior of the parallel programmer drastically? if anyone knows about what i should do please contact me.

here is the original parallel cable, i removed the cover exposing the wires... just wondering why there are fewer than 25 cables?
next i soldered 2 470 ohm resistors onto pin 1 and 2 as in the guide.
here is my completed parallel programmer. pin 11 has an incorrect 220 K ohm resistor, I'm told by kg4wsv and Adilson Akashi (link) that i should correct this by soldering two 470 ohm resistors in parallel... but it's almost the weekend and i will get a chance to buy a bunch of 220 ohm resistors from my electronics shop :) thanks thou...
next i just cleaned up a bit my placing some plastic sleaves over the exposed wires so that they wouldn't touch
so this weekend i will get the 220 ohm resistor, replace the 220 K ohm resistor, then us test it, programming the arduino i made then using a glue gun to glue everything inplace in the original packaging.

did the parallel programmer really work???????

I have been at it for a week with no luck..may be i should get it programmed by a pro
