HAVING statement using the column name

In https://github.com/saveenr/usql-tutorial/blob/master/grouping-and-aggregation/intro.md

The statement:
// find all the Regions where the total dwell time is > 200
@output =
SELECT
Region,
SUM(Duration) AS TotalDuration
FROM @searchlog
GROUP BY Region
HAVING TotalDuration > 200;

Error:
Severity Code Description Project File Line Suppression State
Error E_CSC_USER_INVALIDCSHARP: C# error CS0103: The name 'TotatDuration' does not exist in the current context
Description:
C# compiler reported that this expression is not valid C#.
Resolution:
Make sure that a valid C# expression is specified. USQLTutorial C:\Users\bret\Documents\Visual Studio 2015\Projects\USQLTutorial\USQLTutorial\GroupingAggregation.usql 45

should be changed to:
// find all the Regions where the total dwell time is > 200
@output =
SELECT
Region,
SUM(Duration) AS TotalDuration
FROM @searchlog
GROUP BY Region
HAVING SUM(Duration) > 200;
