Thanks for your reply, Helen.

Basically, I want the IB_LookupCombo drop-down list to be in case
insensitive order (otherwise the search doesn't work properly). I
changed my query's Order By clause to Order By Upper(FieldName) but
obviously IBO replaces it with it's own standard Order By FieldName.

You have effectively answered my query in that I now understand that
you have to use a dummy upper case column. This seems a bit messy
especially when you want to be able to order by/search multiple
columns.

I was hoping that there was a simple way to specify that the order
was to be case insensitive.

Is there a way to manually configure a IB_LookupCombo/IB_Query to be
able to correctly search a mixed case drop-down list?

Regards

Bob
