I found an article here about how to display help dialog when a button is pressed, followed this guide here:
Now I need to be able to show 3 different help text, or images in my case, depending on what value is selected in a choice control.
This is how the client click looks like on the button
And this is the HTML source of the Rich Text control that is storing the images
Is there any way that I can change the Topic_2_help to Topic_1_help or Topic_3_help based on a value from another control?
