Thank you Charles Kenyon

How did you get your page tabs to trigger an event?

I downloaded your code and find that the setting for my multipage properties are the same as yours. But clicking on the tab on yours triggers an event. Mine does not.

I was unable to run the application through the developer window, so do am not able not see what event gets triggered. Nor do I find any reference in the code for "Page".

Your code does work the way I envisioned mine to work. Being self-taught, there's clearly a fundamental concept I'm missing.

My Plan B is to use layer forms (subforming?) to see if I can achieve the same result.
