		// data structure.
		//
		// This is accomplished by displaying three different datagrids, each bound 
		// by separate stored procedures.  The second and third stored procedures
		// take in input parameters to filter the data, which are determined by 
		// which data item is selected in the prior, or parent, datagrid.
