My J option pane continues to repeat even when a one to three is entered but works if I trigger with isKeyDown

if(difficulty < 1 || difficulty > 3){ break; } this doesn't break even if I enter something over 3

Line 57 kind of negates the whole do loop altogether. However, there are still other issues you need to be aware of. You are parsing input that is not being checked. Issues could be (1) the input returned was null (happens when the user closes the frame by clicking its Close button, the red 'x' button at top right corner of the frame or the user presses the Escape key); or (2) the input is not able to be parsed (happens with invalid input -- any alpha character or any punctuation that is not a plus ('+') or minus ('-') sign at the first character position). Errors from these are the NullPointerException and NumberFormatException exceptions. For lines 52 to 58, try something like this:
?

while (true) {
    String s = JOptionPane.showInputDialog(diff, "What Difficulty? (1-3)");
    if (s != null && s.length() == 1 && "123".indexOf(s) > -1) {
        difficulty = Integer.parseInt(s);
        break;
    }
}
The squareValue input can be coded similarly. Be aware that swing components will not run on any site (including this one) using HTML/javascript. You may want to either use the Greenfoot.ask method to get the input or not use an input box at all and just except a keystroke after prompting for it. It can still be displayed after the input is made.

still repeats itself even if i enter 1-3 which is weird because the squareValue input works and this one works if i have it be triggered by pressing a key if (Greenfoot.isKeyDown("n")){ JFrame diff; diff=new JFrame(); boolean diffSet = false; if(diffSet == false){ diffSet = true; do { difficulty = Integer.parseInt(JOptionPane.showInputDialog(diff,"What Difficulty? (1-3)")); if(difficulty < 1 || difficulty > 3){ break; } break; }while(true); } because that works but the other one doesn't

The code provided by myself was tested before posting. I am quite sure it, by itself, is not the problem. Please show your updated code.
