I placed a Click To reveal tab interaction in my current course however for some reason it does not show when i preview the course from that slide. I checked to see if the items played the entire time during the timeline and they do I just cant figure this out.
Without more details it is impossible to help you. Where did you get that interaction? Did you find instructions to use them? Just inserting them in a cptx file will not be sufficient if you talk about a Click/Reveal from one of the projects packaged with 11.5. Tell which project and slide you used if that is the case. I have explored most of the interactions in those projects, although I never use them myself but create interactions myself.
If you use an interaction downloaded from the eLearning Brothers, contact them on their site.
BTW: do not use the cptl format (since you talk about a template).
