Grouping on Multi-Value parameter

I have a report that groups on a field, AccountNumber (which is a parameter)
I changed this param to a Multi-Value field, but now, whenever the report
runs, it blows up saying it's an invalid datatype for the grouping. I have
the rest figured out (how to parse the comma separated list) but I'm stumped
on this. Any ideas?
I know that when you change a parameter to multi-select, the value is
represented differently even if it's just one field that's being selected -
well, at least I think I know b/c my logic stopped working. I changed the
stored proc to parse the comma-separated values and all was well. So it's
working fine on every report that doesn't involve grouping. But on this one,
it blows up.
Thanks,

If your report dataset is based on SQL 2000/2005 you can prepare SQL
statement like this
SELECT * FROM table WHERE id in (@.MultiValueParam)

Thanks Adam. Actually, I got the IN part to work. I couldn't get it to
work using the exact syntax you used, I had to parse the values out but I got
that to work.
The problem though is that the report creaters grouped on a Parameter as
opposed to a field in the dataset. However, when it was changed to a
multi-valued parameter, the grouping blew up.
I got around it by changing it so that it grouped on a report field instead
of the parameter. Any ideas though on how to get it to group on the
parameter if it's multi-valued?
