How many attempts do you offer for the click box? If it is set to Infinite, the user will have to be successful before being able to proceed.
However, if you have multiple interactive objects on the slide, you have to know that if they execute a 'simple' action (using the dropdown list in the actions accordion) the playhead will be released at the same moment and will continue. If you don't want this to happen, because there are other objects to be clicked (that have the pause at the same time), you need to replace the simple action by a standard advanced action: Why choose Standard over Simple action? - Captivate blog
As for the events that can trigger an action (like Success/Failure): Events and (advanced) Actions - Captivate blog
