regarding interfacing sd card with pic 18f4520

I am interfacing my micro sd card with the above circuit diagram(in the attachment file). I am initializing my sd card with the following sample code, i am displaying the response in my lcd. According to the code i am expecting blank display where as it shows one. which means it is not initialized or card is not accepted.

kindly help me to get me out of this.is there any other resource for interfacing the sd card. i am using 18f4520. my compiler is ccs version 4.057

my code is:


#if defined(__PCM__)
#if defined(__PCH__)
#endif
#endif

#include <stdio.h>
#include <string.h>
#include <mmcsd.c>
#include <input.c>

#use standard_io(B)
#use standard_io(C)
#use standard_io(D)
