error message

[Russ]

I am using a query to get data from various forms that
have data. The forms were made using Pendragon software,
a application for the Palm. When I create a query, the
data imports fine, but if I try to modify the table using
design view, I get the error message saying that Pendragon
can represent the join expression. Howerver, the same
join expression works for all the other forms that I
have. Any help would be greatly appreciated.
