Disable next button until all object states have been achieved

I was wondering if the following process is possible. I have been trying multiple ways to create this effect but none seem to be working.

I have created the following image with icon buttons. I would like users to click on each icon, which would direct them to a different slide, when clicking on the icon again (on the slide the user was directed to) this process would return them to the original slide, with the icon now as a green tick.

This part of the process I have been able to achieve using Execute Advanced Actions, however the next stage I would like to implement is to not allow the ‘Next’ button to be executable until all information buttons have been previewed. This part I can’t seem to get working.

Can anyone give me some pointers. I am very new to developing online training via captivate.
