data grid continued

[Sadhunathan Nadesan]

Aloha,

I'm struggling to get at the data once it is in the grid.  The examples
in the docs do not seem to work (page 59 of the PDF).  Trying something
very simple like this message in the message box

     put the dgHilitedLines of group "DataGrid 1"

Yields:

     Message execution error:
     Error description: Chunk: can't find background

huh?

Can anyone make a suggestion?

Thanks
Sadhu
