Hi Everyone Myself and my colleague have been designing a sudoku game using java. Pretty basic game nothing too fancy, but we have hit a wall and need some help. We have implemented a Hints button in which if you type in the correct number into a selected cell it will go blue if it is correct or red if the answer is incorrect, now we would also like a pop up window to show up if the answer is correct or if it is incorrect to warn the user. How can we go about doing this we have tried but no success. I have attached the java script and html page for you to view. thankyou
