SPI Data Not Received on PIC18F4550 Slave When Using For Loop in Master Code

I am using two pic18f4550 for SPI communication but when I use for loop for following line

 for(loop=0;loop<=x;loop++)
     {
     spidatawrite(send[loop]);
     }

then I am unable to receive data on slave side but when same line with do-while loop is implemented then I receive data on slave side. I am using mikroc compiler. My complete code is given below;

Hi,

There is the slightest possibility that your for loop is not met. Have you tried just doing printf in send[loop] your for loop first? just to check if it really enters.
