It's because you have semicolons after the if(......) statements....I would guess.

Also you have "return=0" which should be "return 0". Hope this helps.

Hi everyone,

Thanks for the syntax help Giles, I got it figured out (had an extra curly bracket in my void mouseClicked section..argh).  I'm going to post my now-working code here, just in case it ever serves to help anyone trying to do something similar.

Code:
/* This applet loads a 1020x600 .jpg with 4 distinct boxes ("regions") in it, and returns an integer between 1 and 4 depending on which "region" is clicked in, or a 0 if the click is not in any of the regions */

PImage a;  // Declare variable "a" of type PImage
int clickedBox;
int XofMouse;
int YofMouse;

void setup() {
  clickedBox = 0;
  size(1020, 600);
  a = loadImage("background.jpg");  
  // Load the image into the program  
}

void draw() {
  image(a, 0, 0); 
}

void mouseClicked() {
  XofMouse = mouseX;
  YofMouse = mouseY;
  clickedBox = whatBox(XofMouse, YofMouse);
  println(clickedBox);
}


int whatBox(int XofMouse, int YofMouse) {
 if (XofMouse>310 && XofMouse<710 && YofMouse>380 && YofMouse<565) {return 1;}
 else if (XofMouse>310 && XofMouse<710 && YofMouse>35 && YofMouse<220) {return 2;}
 else if (XofMouse>35 && XofMouse<250 && YofMouse>36 && YofMouse<564) {return 3;}
 else if (XofMouse>770 && XofMouse<985 && YofMouse>36 && YofMouse<564) {return 4;}
 else {return 0;}
}
