I think you may be overcomplicating this.
Why don't you just place the second text caption on the slide timeline to appear just after the pause point of the button?
That way you won't need to worry about SHOW or HIDE or any Advanced Actions. The timeline pauses at the button so that the user can read the first caption. When user just clicks the button the play head continues playing and they see the second caption appear. You either have another butto to pause the timeline again to allow them to read at leisure, or else allow enough time before the end of the slide is reached.
That will probably be my best option to make the next button pause and unpause the timeline since I want to make sure the user has full control of when they are ready for the text. Since the other ~30 slides already have the next button functioning as that text show/hide/advance key, I was trying to keep the user experience the same on these nine slides if at all possible. This module was previously coded in Flash and is not playing nicely with our new LMS. I'm trying recreate and have it act as similarly as possible in Captivate - at least so we can get a first version rolled out quickly.
Looks like I need to do some more research on how the buttons pause and unpause things so I can get the timing closer. I'm trying it in one of my slides, but either my slide is too long (12 seconds) or I'm not understanding how to set this so that it is seemless and the button causes the slide to move foward. I know my ways were overthinking it a bit, but they still should have worked, right?
If you want me to have a look at your advanced action, please post a screenshot,
Thanks Lilibiri, I'm good though. I was having a rough start because it just didn't make sense as to why I was ending my actions with If v_click=2, then show TC1, and it wasn't working. I had to change it to if v_click=1, then show TC1 which didn't make sense to me until I thought it through a few more times and came to the conclusion of it's a timing thing. Now, if only that file hadn't corrupted I'd be good to go!
