In the story map I have 12 tabs (introduction tab, the other 11 are a park each).
When the story map is first opened, if you click one of the tabs - the map displayed on that tab will be the map that is displayed in tab 2 (in my case - a park called Awakairangi). This is the same for any tab that is pressed (other than Awakairangi).
I can provide further links etc if required - just let me know.
Other than that everything works fantastic and members of the public have complimented the application
Thanks and hope to hear from you soon.
