Trubble with Triggers! (and layers)

Hi John. It's always best to include a copy of your .story file if possible. There are many interacting pieces to a Storyline project, and a description may not cover all the possibilities.  Based on your image, are you trying to trigger your Start Button layer from itself (the Show this layer part)? Perhaps disable that trigger and try triggering the Show layer {Start Button layer} from the base layer, where the intro text lives instead.

Alternatively, just put the start button on the same layer and timeline as the intro text. Then, drag the start button entry on the timeline to the right, so it begins at 5 seconds. That way it won't appear until that point. Note, there is an icon at the top right of the timeline area (left-most of the two) that toggles between showing all timeline objects, and only those active at the current time index, where the vertical blue line crosses the timeline. That can help you visualize what is visible at any given time.
