Hello Andy,
What "name" are you looking for? If it is the title in the browser tab, you can find it with a small JavaScript.
If is the Text you put in the title area of the screen, you can also use JavaScript to find it (but now it will be more specific to the template you are using, and the most probable is that you will have to pass it through input parameter).
The name of the page itself IS the name in the flow, as far as I know.
So, what is the name you want?
Cheers
Eduardo Jauch
EDIT
Forgot to mention that GetPageName returns the flow page name, but if there is name clash, this name can be different from what you see in Service Studio.
