Microcontroller with 2 way paging application problem

e = s 'Copy s to byte e
...
...
...
e=s

on those two you missed the semicolon. As for the rest, try simple code, 4-5 preambles and a byte to see if you have good communication. Then try two bytes different this time. Your code needs a lot of examination and right now I can't read it.
