ok Ive made a sample of it im sure its messy but its just sample.
First create a global variable in the event sheet call correct
create one text and one button change all button to check box (Button>properties>Type to checkbox.
Drag clone three button. click on each of the button and change their instance number (Button>properties>ID(optional) to 1 , 2 , 3. Go to your event sheet and create an group event call it First question.
First line in the group Event first question.
System>compare variable(now it should have correct variable leave it at =0. For action go to Text>set text (to the question you want)
next line do Button>Pick by instance to 1 And add in System >compare variable to correct 0. For action Set button>Set text "to what ever you want"
Do repeat for 2 3 button
For the correct answer add this to next line Button>pick by instance(#) add in another condition Button>if checked Add another condition System>global variable=0. FOr action SET text to Correct Add another action System Add variable to correct 1 add another action Button unchecked
Do the same for second question only changing the system>Global variable correct to equal 1.
So on so on... again this is what i found it may be messy but it does work. This is the basic ive found any more question ill try to answer.
