using opencl kernel function parameter & ptxas ptx problem

opencl kernel function include a lot of parameters.

And I want to control the parameter.

Some parameters are cl_mem, another parametsers are cl_int or cl_long in opencl application program.
Then opencl kernel is received the data.

And then I control a kernel source code to use parameter.

For example,

void subrectEncode32(
					__global int* resDestoffset,
					__global ulong *dest,		
					__global ulong *subrectData,
					const int w, const int h, 
					ulong bg,  int mono)
                       int sum;
                       int yH = get_group_id(0);	
	             int xW = get_local_id(0);	

                        if(mono == 1)        // ptxas ptx input error
                               sum = w+h;
                               sum = w;

                        for(int i = yH; i < h; i++)   // also ptxas ptx input error
                              //test code...

I want to comparison the parameter and integer.
And I want to use add number to parameters.

What is my problem? Advise to me…
