Launch MS Word.txt from Help File (ShellExecute Macro)

I know about the ShellExecute API. However, I need to launch a Microsoft Word Document when the user clicks on a hotspot in the Help File. I can't seem to get the proper string set for the macro.

ShellExecute(FileName,[options[,Show-Flag[,Operation[,path[,topic-id]]]]])

I have tried several ways but I keep getting errors

I think the following should work

ShellExecute("Test.Doc",,5,"Open","C:\My Documents",1)

Any ideas would be great. Remember, I am executing this from the help file which is a macro and not from VB!!!!!!
