Disable Button after it is clicked

What is the action that is already triggered by that shape button? There is no reason normally to have a conditional action, if you only want to execute one command and disable that button that has been clicked. Since you talk about multiple buttons, do you have to track also if all buttons have been clicked? Have something happen when they all have been clicked?

Depending on the answer to my first question (which action already to be triggered), it could be better to use a shared than an advanced action.

Hi, you can achieve this by using advanced actions. Set up a new advanced action to perform the action you wish the button to take when clicked and then the next action in the advanced action should be 'disable'. Be mindful that if the learner then returns to that screen the button will be disabled, to make it active again you could add another advanced action to 'enable' it and add this at the slide entry level.
