Почему отладчик ругается на процедуру в программе на Allegro?

Пишу программу на C в связке с библиотекой Allegro в Visual Studio. Всё прекрасно, но в трёх подобных процедурах отладчик ругается в одном и том же месте. Сама прога не работает. Ругается в функции void RNear и ещё двух таких же в цикле
for (int k = 0; k < 8; k++)
	if (red[i].cot[k] = red[j].ID)
		kot = true;
, но с другими аргументами.
Вот код.
#include <allegro5/allegro.h>
#include <allegro5/allegro_primitives.h>
#include "objects.h"
#include <math.h>

//objects.h
struct RGB
{
	int ID;
	int x;
	int y;
	int speed;
	int boundxmin;
	int boundxmax;

	int boundymax;
	int cot[8];
};
//objects.h end

так и должно быть?
//Searsh Red nearly
if (rd[0])
  {
    for (int i = 0; i < rSize; i++)
      for (int j = 0; j < rSize - 1; i++)
//... 
//Searsh Green nearly
 Аналогично
//Searsh Blue nearly
...

См. вложенный цикл. Нужно j++

И еще
for (int k = 0; k < 8; k++)
  if (red[i].cot[k] = red[j].ID)
    kot = true;


//...
else if (a = b)
//...

присвоение ( = ) в условии, а не проверка на равенство ( == )
