if else statement wont work java

Question

The question field should contain 36 questions, the answer to these question are on the 36 buttons in the grid.

When the user selects the clicks the correct button answer the button is taken off the grid, the aim is to clear the grid so the grid is empty.

if the user clicks an incorrect button the game restarts.

i am having a problem with adding the question label.

the question field should display 36 question starting with what is 0 + 1 when the user clicks the correct button it then shows question 2 shows in the field which is what is 1+1 and so till question 36

i have tried to get this by Changing this line of code

 gui.statusLabel.setText("what is 0+ 1" + gui.buttonCounter);

to this:

 gui.statusLabel.setText("what is " + gui.buttonCounter + "+ 1");

but the games doesnt work properly although the correct answer is selected the code keeps saying doing the "else" in this code ie. Incorrect button clicked, start again: what is 0+ 1

    if(clickedNumber == gui.buttonCounter){
        gui.buttonCounter++;
        buttonClicked.setText("");//optional - clears correct selection
        if(gui.buttonCounter > gui.ROWS*gui.COLUMNS) gui.reset();
        gui.statusLabel.setText("what is 0+ 1" + gui.buttonCounter);
    } else {
        gui.reset();
        gui.statusLabel.setText("Incorrect button clicked, start again: what is 0+ 1");
    }

    }
}

how do i fix this? so when i click the correct answer button it moves to the next question and does not display Incorrect button clicked, start again: what is 0+ 1.
