Question : Parameters not being passed to stored procedure using vb.net

Below is my code which is attempting to pass two parameters to a stored procedure within a sql 2000 database. The parameters expected by the stored procedure are @dateTo and @dateFrom, they are both of type varchar(10).

When I execute my code, vb.net pops up an error to say that the stored procedure 'usp_createFocusView' expects parameter @dateFrom but it has not been supplied.

Where am I going wrong as the parameters are clearly not being passed thru vb.net to the stored procedure?

Many thanks
