[Zope] selecting tinytableplus to update by parameter

[John]

Hi
I'm new to zope/python and hope this is fairly easy - I want to update
a TinyTablePlus table from a script.  So the following will do what I
want on the table 'igrid'.

context.igrid.setRow(number=number,score=newscore)

But how can I do this on different tables where the table is passed to
the script as a parameter - instead of igrid  I want to include the
value of the parameter.


thanks, John
