Serial com: in need of help

[mbw123]

This code that runs on two 16F628A's is not working. There are four buttons on the transmitter that control the five pins on the receiver. A packet is sent out for each change in the button state. Please help!
Thanks.

Thanks again!

Some IF THEN statement are weird to me

if (PORTA.0 = 0 && sone = 0) then

Should be

if (PORTA.0 = 0) AND (sone = 0) then

OR

if (PORTA.0 = 0) && (sone = 0) then

There's few missing info.
Config Fuse setting.
Internal OSC or external?
wich speed?
Schematic?
