  You'll need to provide a little more information about how you have the buttons hooked up and where the messages come from. Break your problem down into smaller tasks, and ask when you get stuck on those.
  
  Your first micro goal should be to display the results of pressing buttons on the debug terminal, with a display like
  %00110110
  that shows a 0 or a 1 for each switch.
  
  Then, see if you can display "hello" on each line of your LCD screen.
  
  Then, display the switch states (e.g. , like %00110110) on the LCD screen as well asf on the Debug screen.
  
  Then you are ready for the messages finale with a modicum of hair remaining!

  this is basically what your after i think. not sure on the display constants / layout but this work on what i have to hand at the mo which is a 16*2 serial. gives you something to play with .
  
  
  
  
  
  ' {$STAMP BS2}
  ' {$PBASIC 2.5}
  '******************************************display constants
  
  '16468 set up 9600 8 data bits no parity
  LCD_CLS············ CON 1
  scroll_l········· CON 24
  n96n_Baud········· CON 16468
  
  'var
  pin_status· VAR Byte· 'test routine variable
  
  '*******************************************routine start
  
  DIRS=%1111111100000000······· 'pins 0-7 inputs, pins 8-15 outp
  PAUSE 1000
  SEROUT 16,n96n_baud, [noparse][[/noparse]254,132,"TEST MODE "]
  
  
  TOP:
  pin_status=INL········· 'read the value of the inputs into pin_status
  
  SEROUT 16,n96n_baud, [noparse][[/noparse]254,194,"I/P=",DEC INL.BIT0,DEC INL.BIT1,DEC INL.BIT2,DEC INL.BIT3,DEC INL.BIT4,DEC INL.BIT5,DEC INL.BIT6,DEC INL.BIT7,"······················ "]
  ······'display the active i/ps
  
  GOTO TOP········· 'repeat

  It's much easier than you're making it. Try this:
  
  · SEROUT pin, baud, [noparse][[/noparse]254, 194, BIN8 pin_status]

  Thanks for the help.
  
  I look at the suggestions and I wonder what the hell I was thinking!
  
  Tracy, thanks for the walk through.
  
  weydev, thanks for the example and
  
  John, I appreciate your help as well.
  
  I just wish I had a better handle on the whole programming thing. My mind doesn't seem to grasp the "obvious"
  
  Is there any resource for the programming challenged? I have the parallax book, I have Scott Edwards Stamp book, and both of them seem to gloss over things that I don't seem to understand.
  
  any help would be appreciated.
  
  thanks!

  I think you'll find experience is the best teacher. Keep working with BASIC Stamps, spend some time at Tracy's (way cool) web site, and it will all come together.
