TRANMITT

Question

I have 2 different addresses on my tranmitters, on my receiver I am using a routine to power the corresponding addresses one at a time and receiving a variable from the tranmitter.  It checks one address and gets the correct value which I am displaying on my LCD, the other tranmitter it is not being checked apparantely.  The value of the first transmitter is getting copied into the second transmitter value.  I have separate routines for the transmitters as they are bein run by an ATMEGA each.  The receiver is controlled by another ATMEGA and is supposed to switch addresses to check both tranmitters one at a time.  Any suggestions?  I will be writing a routine on the tranmitter side to alternate sending a low signal to enable the transmit and high on the other to disable and vice versa.
