Xbee Sketch Issue

hi, developing sketch of communication between 5 xbees s1, 4 of them connected arduino fio board , 3v7 power source, other 1 connected arduino uno r3 2 shields (xbee shield https://www.sparkfun.com/products/10854 , micro sd shield https://www.sparkfun.com/products/9802).

the aim of project show in 20x4 lcd display values obtained 4 air pressure sensors (each 1 connected arduino fio board)

the codes in pastebindotcom because said post exceeded number of characters, , are:

for receiver:
http://pastebin.com/jxvkvzag

for transmitter:
http://pastebin.com/pgwaarrh

in transmitter value changes d inbyte =='value'


i tested sketch using potentiometers using a1, gnd , 3v3 pins of each arduino fio board. had issues it, values got reflected between them (for example third value goes x value displays fourth value, , of them have same issue), , total sequence takes 6 seconds display values.

i have purchased arduino wireless sd shield http://arduino.cc/en/main/arduinowirelessshield have no idea how develop code it. have been looking information info found shows configurations not creation of sketch. code have posted got developed me , friend, difficult because beginners in arduino , in programming. , @ point got stuck in developing of sketch.

so if possible of me giving me clue change in code or in hardware great.

i hope can me, in advance attention , help. i'm sorry bad english.
