Obscure SQL Server error when task fails in my dts

Does anyone have any insight to this error:
"Duplicate column name resolution could not be done because the ordinal specified a column of a different name"

I googled it and got one result with no resolution.
I get this error from SQL Server when a task in my dts package fails. My dts package is attempting to update records whose fields have changed based on a specified criteria.

Any help would be greatly appreciated.

TIA,
Jennifer
