Default Looping over nodes of a cell (UDF) error

hi, I have following EXECUTE_ON_DEMAND udf for post-processing. I would like to loop over nodes of certain cells in the domain. When I interpret this udf, the error comes "non-integer subscript expression: unsigned char" for the line containing "c_node_loop(c,t,n)". I would like to know why this error message is coming? Is there any other way of looping over nodes? Please let me know as soon as possible. Thanking you in advance.

#include "udf.h" DEFINE_ON_DEMAND(analysis) {

Domain *d;

Thread *t;

cell_t c;

Node *node;

int n;

real xc[ND_ND];

d = Get_Domain(1);

thread_loop_c(t,d)

{

begin_c_loop(c,t)

{

C_CENTROID(xc,c,t);

if(fabs(xc[2]-0.135)<0.0002)

{

c_node_loop(c,t,n)

{printf(" %d ",n);}

}

}

end_c_loop(c,t)

} }

I think you cant run this udf in interpreted mode. I compiled it with no error.
