Background(image) not working

void mousePressed() {
if ( state == 0 ) {
if ( over(x1, y1, w1, h1) ) state = 1;
if ( over(x2, y2, w2, h2) ) state = 2;
if ( over(x3, y3, w3, h3) ) state = 3;
if ( over(x4, y4, w4, h4) ) state = 4; }

else {

if ( over(x5, y5, w5, h5) ) state = 0;

}

}

Guess this can still go wrong because of missing else if within the main if

Not in this code but:
when x1 and x3 overlap both buttons would be executed
