How do I Use the same object to control 2 other objects

Using the same object to control 2 other objects. this one is hard to explain for a beginner. My game is a platformer. The aim of the game is to collect coins that are hidden in chests. To open the chest you have to answer a math question. I have successfully got the question working thanks to bbenny93. My issue now is that when i goto the first chest and answer the question both of the chests will open and give you a coin. I probably doing it all wrong. Do i have to create seperate question popups for each chest or can i use the same one but when answered they only open up 1 chest? Ive attatched the CAPX file so you can have a look. Thank you in advance.

Basic exercise in using Instances and picking Instances.

Notice that there is only 1 chest sprite, 1 coin sprite and 1 check sprite. Hence, there is only 1 event / game action, yet it works for all.

This principle is the whole big idea behind the Construct 2 engine, and if you ask me, the beauty of it.

Give your chests their own instance variables instead of using global. Then amend the events for the chests to use their instance variables.

sorry for the late reply. Thanks a lot guys. So much to learn but this opens up so many possibilities. Thanks again!
