 To check for errors in the report's script, click the **Validate** button. The validation result is displayed in the errors panel at the bottom of the Script Editor. Double-click the error item in the panel's list to go to the corresponding line of code. If all scripts are valid, the errors panel is empty.

-## <a name="example"/>Example: Custom Summary
-This example demonstrates how to display the total number of product unit packs in a group.
-
-To perform this, execute steps similar to the ones described in [Calculating Summaries](shaping-data/calculating-summaries.md), except that for the summary field, you should set the **Function** property to **Custom**.

-Then, the additional events are added to the label's **Scripts** property.

-You can handle these events in the following way.
-
-**C#**
-
-```csharp
-
-// Declare a summary and a pack.
-double totalUnits = 0;
-double pack = 15;
-
-private void label1_SummaryReset(object sender, System.EventArgs e) {
-    // Reset the result each time a group is printed.
-    totalUnits = 0;
-}
-
-private void label1_SummaryRowChanged(object sender, System.EventArgs e) {
-    // Calculate a summary.
-    totalUnits += Convert.ToDouble(GetCurrentColumnValue("UnitsOnOrder"));
-}
-
-private void label1_SummaryGetResult(object sender, 
-DevExpress.XtraReports.UI.SummaryGetResultEventArgs e) {
-    // Round the result, so that a pack will be taken into account 
-    // even if it contains only one unit.
-    e.Result = Math.Ceiling(totalUnits / pack);
-    e.Handled = true;
-}
-
-```
-**VB.NET**
-
-```vb
-
-' Declare a summary and a pack.
-Private totalUnits As Double = 0
-Private pack As Double = 15
-
-Private Sub label1_SummaryReset(ByVal sender As Object, ByVal e As System.EventArgs)
-    ' Reset the result each time a group is printed.
-    totalUnits = 0
-End Sub
-
