You already closed the if statements with ) so everything after that is lost. You don't even need all those ( ) brackets.

If you have declared imageIndex globally you also don't want to put an int in front of that. But perhaps it's intended as a local variable then it's all right.

Finally your third line is missing something, most likely the acual image() method.

Adapted Code

1. if (x>0 && x<67 && y>0 && y<38) {
2.   int imageIndex = 0;
3.   image(images[imageIndex], 0, 0);
4. }

i f ((x > 0) && (x < 67)) && ((y > 0) && (y < 38))
if ((x > 0) && (x < 67)) && ((y > 0) && (y < 38))
if ((x > 0) && (x < 67)) && ((y > 0) && (y < 38))

As said, your parentheses are both highly redundant, and incomplete: you would need to write:
if (((x > 0) && (x < 67)) && ((y > 0) && (y < 38)))
ie. external parentheses wrapping the whole expression, the only ones that are mandatory!
And I prefer the simpler version of amnon.owed. As long as you use the same operator, there will be no ambiguity with the priorities, there.

Brilliant. Thank you both so much. That fixed it. :)
