ID topic not responding calling a custom .CHM help file

[Sergi Gàmiz Ribelles]

I'm writting a .CHM help file with 'HelpNDoc Personal Edition'; each topic has its Context ID, but  the mapbasic statement

' Set Window Help File "mycustomhelp.chm" ID 10 '

doesn't redirect me to the topic: MapInfo shows an error window

 Qt? error: "Error reading the file of collection '.....mycustomhelp.chm' ".

The same statement without the ID clause reads and shows mycustomhelp file correctly.

Which is the solution, please?

Thank you.

SOLVED. the right command is  Set Window Help File "mycustomhelp.chm" ID "10" 

The IDnumber beetwen quoted marks, because IDs are strings in  HelpNDoc.
