Trigger problems, changing the state of a button.

I have difficulties to change the state of a button after passing a test with a score of 5.
There are 5 buttons and there are 5 question banks, you must change the button from the hidden state to visible after answering 5 questions.
There are 5 variables for each button, only if they pass the test will the state change, I already tried with false and true, with text or numeric and the state does not change ...

I have not tried with javascript, since I am not proficient in programming
What can I do or how do I solve it?
thanks for your comments
