open html file from script in Filemaker GO

[muddylanding]

I have an html document stored on an iOS device in the Filemaker Go documents folder. File name "HomePage.html"

I would like to open the document from Filemaker Go using a scripted button either in the browser or Safari.  What is the best way to open an html document in Filemaker Go and what is the correct path name of the file when it is stored in the Filemaker Go documents folder?
