Debugging DataGrid script

I think this line is incorrect for at least one & possibly 2 reasons.

Firstly, the "firstLineContainsHeaders" needs to be in quotes.
Secondly, I'm not sure if you can leave a space before the opening
square bracket.

So try this:

set the dgText["firstLineContainsHeaders"] of grp "HelpDataGrid" of
card "Help" to tHelpLines

Without knowing exactly how the data grid works, I can't see that it
would be a problem setting the data while on another card. This is
just a standard property setting command which should work fine,
unless there is something in the relevant setProp handler that expects
the grid to be on the current card. If this is the case, you could
lock screen, go to the grid card, populate the grid, then go back to
the original card without any of this having been visible to your
app's users.

Cheers,
