oh yeh i see it, one problem tho, i would like to know how to do it with the flowsheet software, i think i get whats going on tho. when the button is pressed it inputs a column and a row and works out which is the right button being pressed from that right? well that uses 7 inputs, i might be able to get 7 inputs if i get rid of the 3 i was already using but is there a way to use only four?

well these chips have analoge input so i might able to do something with that, but for what its worth i recon i could use all the pins. check out this bit of flowchart i made, is this how it should work? pin 0-2 = columns 1-3, and pins 3-6 = rows 1-*. variables 10=* 11=#. b0 = button being pressed.
