Is it possible to use if/else if statements to check where the mouse is being pressed

Hi,
Just recently getting into OOP, I've been experimenting with using functions - instead of having unweildy code in the body of void draw().
I have the ball changing size (ballSize) depending on what bar is pressed in the first 'if' statement. I want the ball to drop if the mouse is pressed while the ellipse/ball is being drawn around it
Snippet:
- void mousePressed() {
- //Check if the Mouse is Pressed on the Bars
- for(int i = 0; i < 5; i++) {
- if(mouseX > mySizeLevel.rectXY[i][0]
- && mouseX < mySizeLevel.rectXY[i][0] + mySizeLevel.rectW[i]
- && mouseY > mySizeLevel.rectXY[i][1]
- && mouseY < mySizeLevel.rectXY[i][1] + mySizeLevel.rectH[i]) {
- ballSize = 50-5*i;
- mySizeLevel.index = i + 1;
- println(mySizeLevel.index);
- } else if (mouseX > aimX && mouseX < aimX + aimW
- && mouseY > aimY && mouseY < aimY + aimH) {
- myballDrop.fall;
- }
- }
- }
On line 15 (above), I've referenced the function 'fall'. This is under the 'ballDrop' class, and I'm wanting it to just increment the Y-axis.
The arguments check if the mouse is being clicked within the dimensions of the rectangle the ball starts in, but I'm still getting a syntax error.
Thank you very much in advance.
Full code:
- //Class for the Size of the Ball
- sizeLevel mySizeLevel; //why does this line have to be entered?
- triangleTarget mytriangleTarget;

- //Score Area Spec
- int scoreX = 100, scoreY = 20, scoreW = 400, scoreH = 30;
- //Aim Area Spec
- int aimX = 100, aimY = 60, aimW = 400, aimH = 70;
- //Target Area Spec
- int targetX = 100,targetY = 130, targetW = 400, targetH = 250;
- //Ball Size
- int ballX = 200, ballY = 100, ballSize = 50;
- void setup() {
