Connector

Hello i am new to developing jitter c-externals...

I am on Windows 7 using Visual Studio C++ 2010 Express and the MAXSDK 5.1.7

I am trying to make some kind of jitter external and therefor i defined a struct:

typedef struct pixels {
    long greyscalevalue;
    float posX;
    float posY;
    float posZ;
} t_pixel;

but when i try to use the struct in following code: `void connector_jit_calculate_ndim(t_connector_jit_gl_pixelgrafix *x, long dim, long *dimsize, long planecount, t_jit_matrix_info *in1_minfo, char *bip1, t_jit_matrix_info *in2_minfo, char *bip2, t_jit_matrix_info *out_minfo, char *bop) {

    long i, j,avalue, rvalue, gvalue, bvalue;

            width = dimsize[0];

            height = dimsize[1];

            for(i = 0; i < height; i++) {

                ip = bip1 + i*in1_minfo->dimstride[1];            

                for(j = 0; j < width; j++) {

                    avalue = (long) (*ip++);

                    rvalue = (long) (*ip++);

                    gvalue = (long) (*ip++);

                    bvalue = (long) (*ip++);

pixel.greyscalevalue = rvalue + gvalue + bvalue;

                    pixel.posX = (float) 0;

                    pixel.posY = (float) 0;

                    pixel.posZ = (float) 0;

Visual Studio tells me a message Error: identifier "pixel" is undefined,Error: identifier "rvalue" is undefined,Error: identifier "gvalue" is undefined and Error: identifier "bvalue" is undefined. My C skills are not that good as yet but i hope someone can give me a hint how to solve this error.
