cryRpt.Load(Application.StartupPath & "\SpecificAreaReport.rpt")
            
            Dim crParameterFieldDefinitions As ParameterFieldDefinitions
            Dim crParameterFieldDefinition As ParameterFieldDefinition
            Dim crParameterValues As New ParameterValues
            Dim crParameterDiscreteValue As New ParameterDiscreteValue

            crParameterDiscreteValue.Value = Me.AreaNameTextBox.Text
            crParameterFieldDefinitions = cryRpt.DataDefinition.ParameterFields
            crParameterFieldDefinition = crParameterFieldDefinitions.Item("empID")
            crParameterValues = crParameterFieldDefinition.CurrentValues
            crParameterValues.Clear()
            crParameterValues.Add(crParameterDiscreteValue)
