Initialize object wont work in second iteration of function

Unity Engine

so I have a function with nested loops to initialize an object over and over in various places. The function does work the first time, but when I call it again after changing the values of the parameters it wont run, it just gets skipped over entirely.

function Start(){

//var startPoint = new Array(0, 0, 0);
//var endPoint = new Array(width, height, depth);

var startPoint = new int[3];
var endPoint = new int[3];
startPoint = [0,0,0];
endPoint = [width, height, depth];
//endPoint = [Random.Range(-10,10), Random.Range(-10,10), Random.Range(-10,10)];

//sectionCheck = checkSection(startPoint, endPoint);
startPoint = createSection(startPoint, endPoint);
print('first start: ' + startPoint[0]);
startPoint = planSection(startPoint, endPoint);
print('2cd start: ' + startPoint[0]);
endPoint[0] = 5;
endPoint[1] = 4;
endPoint[2] = 3;
startPoint = createSection(startPoint, endPoint); 
print('3rd start: ' + startPoint[0]);
}



function createSection(start, end){
//print(start[0]);
    for(var x = start[0]; x < end[0]; x++){
   		for(var y = start[1]; y < end[1]; y++){
       		for(var z = start[2]; z < end[2]; z++){
       			print('new brick'+x);
             	Instantiate(brick, Vector3(x,y,z), Quaternion.identity);
       		}
   		}
	}
    start = end;
	return start;
}

print(‘new brick’+x); fails to run the second time I call the function. I have checked to make sure the parameters have values it needs. Is there something I am not understanding about calling functions?

Thanks a lot

Are you sure that start[0] through start[2] are larger than end[0] through end[2}?

What are the starting values for width, height and depth?
