How to get Error Message to Pop Up Drag and Drop

Hi Sarah,

You can make the Incorrect layer appear based on the state of the dropped item. For each pipe you need to create a state "Drop Incorrect". Once you have that state for each pipe, you can add an object trigger to a pipe that states [Show layer incorrect > When the state of (pipe object) is Drop Incorrect]. Then, on the Incorrect layer you have to add a trigger that states [Set state of (pipe object) to Normal when the timeline ends on layer incorrect if the state of (pipe object) if the state of  (pipe object)  = Drop Incorrect] The layer "Incorrect" should be set to "Hide slide layer when timeline finishes" in the Slide layer properties. The attachment has a new scene with a working model.
