Hey guys!

For some reason the square grid isn't showing up even though I checked (via println) that the rect(x, y, size, size) function is getting the correct values...I don't understand why when I type rect(115, 115, 20, 20) I get the square come up but when I feed it those numbers with variables I get no square. Am I missing something really simple?

1. ElectrodeSq[][] s;
2. int numCols = 2;
3. int numRows = 3;
4. float gapX, gapY;
5. float electSize = 20;
6. float x, y;
7. float chunkX;
8. float chunkY;
9. color background0 = color(95,95,91);
10. color background1 = color(178, 172, 172);
11. color electColor = color(232, 210, 12);
12. void setup() {
13.   size(600,400);
14.  
15.   gapX = electSize/2 + 5;
16.   gapY = electSize/2 + 5;
17.   s = new ElectrodeSq[numCols][numRows];
18.  
19.   for(int i=0;i<numCols; i++) {
20.     for(int j=0; j<numRows; j++) {
21.       s[i][j] = new ElectrodeSq(i, j);
22.     }
23.   }
24.   noLoop();
25. }
26. void draw() {
27.   for(int i=0; i<numCols; i++) {
28.     for(int j=0; j<numRows; j++) {
29.       x = 100 + gapX;
30.       y = 100 + gapY;
31.       s[i][j].display();
32.       gapY+=electSize + 5;
33.     }
34.   gapX+= electSize + 5;   
35.   }
36. }
37. ElectrodeSq[][] s;

66.       y = 100 + gapY;
67.       s[i][j].display();
68.       gapY+=electSize + 5;
69.     }
