Xbee to Xbee - communication failure

hi , last school year , i'm working arduino , xbee project. ive got 2 arduino uno's , 2 xbee schields .

i'm making boat , have boat 2 motors in , , remote control . each has 1 uno , 1 xbee.

i'll made 2 programs 1 program reads 2 potentiometers , , calculates speed.. works pretty , when open serial monitor , move 1 of potentiometers sends serial information : (l249r249)
l & r left , right motor , wanted .

code: [select]

 //declaratie

 int analogpin1 = 4;
 int analogpin2 = 5;
 int dl = 0;
 int dr = 0;
 int linksemotor = 0;
 int rechtsemotor= 0;
 int analogl = 5;
 int analogr = 6;
 int snelheidbegin = 0;
 int richtingbegin = 0;
 
 
void setup()                          // toekennen functie van de i/o  
 {
   
 
 pinmode(analogpin1, input);
 pinmode(analogpin2, input);
 pinmode(analogl,output);
 pinmode(analogr,output);
 
 serial.begin(9600);                 // initializeer de seriele communicatie
 
 }                                   // einde van void setup

void loop()
   {
   int snelheid = map(analogread(analogpin1), 0, 1023, 0, 499);
   int richting = analogread(analogpin2);
 
   if (abs(snelheidbegin - snelheid)> 2 || abs(richtingbegin - richting)>2)
   {
   snelheidbegin = snelheid;
   richtingbegin = richting;
   
   if ((richting > 499) && (richting < 524)) {
   dl = 0;
   dr = 0;
   }
   else if (richting < 500)  {
   dl = 499 - richting;
   }  
   else {
   dr = richting - 524;
   }
   if (dl > snelheid){
   dl = snelheid;
   }
   if (dr > snelheid){
   dr = snelheid;
   }
   
   linksemotor = snelheid - dl;
   rechtsemotor = snelheid - dr;
 
   serial.print("(");
   serial.print("l");
   serial.print(linksemotor/2);
   serial.print("r");
   serial.print(rechtsemotor/2);
   serial.print(")");
   delay (50);
   }                                 // einde van   if(snelheidbegin != snelheid || richtingbegin != richting)
   
   
 }                                   // einde van voidloop
 
     

   
   

in mij other arduino have program must recieve information , use pwm control motors of boat

when open serial monitor , , type : (l0r249)
the left motor stand still , , right motor rotate @ max speed , can type every singal , works fine.

but when put jumpers on xbee , , try programs , nothing moves , recieve led  on arduino motors isn't on or blinking ...

i configurated xbee's ctu , tested program , worked : http://arduino.cc/it/guide/arduinoxbeeshield

so dont .. got right information send , recieve program works perfect , xbee's configurated perfect , test program works al dont ..



i hope knows why ..

already & grtz belgium !

already & grtz belgium !

don't use capital letters start sentences in belgium? or, shift key broken?

i hope knows why ..

i'm going karmac magnificent impression, , it's line 78 needs changed.

if, rather guesses, want real help, posting code might idea.
