If you are calling a stored procedure, in addition to the NULL issue someone mentioned above, there is a type mismatch issue. For instance I was getting the "Expects parameter that is not supplied" error, when I was supplying the parameter.

After pulling my hair out for a while I found that the procedure had an input parameter of nvarchar(50) and I was passing a string that was longer than that. Apparently any kind of mismatch is reported the same as not providing (which in a way I suppose it is).

So you may want to double check data types and sizes on both ends.
