I want to make 2 button for every question, a button called check button and another button called next button.
The function of check button is to check the answer for 1 question (correct or wrong). If the answer is correct/wrong, it will show the feedback on pop up page.
And the function of next button is to go to the next question, but if the check button has not been pressed, it will show the pop up message (Please click the check button first)
The question is how to make the check button and the next button can work ?
