If:
21_Market_Book.htm is the start page (when you Generate, the
first window is WebHelp General - WebHelp and the first field is
"Select Output Folder and Start Page"),
Then:
The developers should call:
21_Market_Book.htm#WhateverTheNameOfTheScreenIs.htm
If you have a merged project, you and the developers need to
set up a mapping file to identify which project folder contains the
target screen/topic (that is, the topic would be within
"mergedProjects/ProjectFolderName," below the root folder where the
21_Market_Book.htm resides). What we use is a text file called
form_path.txt, with a simple CSV structure like:
WhateverTheNameOfTheScreenIs,
mergedProjects\ProjectFolderName
Good luck,
