Trigger quiz radio button to turn green if correct and red if wron

Hi XAn,

• Select each radio button object and edit it's states. Add two new states named "correct" and "incorrect". Change the radio fill to color of choice.

Correct feedback layer:

• On the Correct layer, set a trigger to change the correct radio button to the new "correct" state when the timeline starts. 
• If the learner chose correctly, their choice will change to green.

• Change the correct radio button to "correct" (to show immediate visual feedback). Same trigger as above.
• Add triggers that change the state of each of the incorrect radio buttons to "incorrect" if they were selected. Ex: Change the state of [Radio Button 1] to "incorrect" when the timeline starts IF [Radio Button 1] is equal to "selected" 

That should work.

Works perfectly. Thank you!

I'm also trying to figure out how to replace the stock radio buttons with custom buttons.

Currently, the default radio buttons either in a Quiz template or inserting them by going to the Insert tab > Buttons > Radio Buttons are all standard in design. There are quite a few changes to the colors and styles though.

You can create custom buttons as well. Just build out your base shape/style, add the appropriate states including what it looks like when Selected. 

Thanks Kevin. I'm not quite sure how to swap out the stock radio buttons for custom buttons. Is that done by right clicking on the stock radios and changing button sets?
