Why Doesn't This Query Run??

Hi can any one see why this will now run when sent to the server. Don't worry about the parameters as these are replaced at runtime in a c# app I have created.

It is not the easiest to read but your help is appreciated.




Code Snippet
/* Create new table of dates using the Week Ending date selected by the user
This is a list of week ending dates between the start and end dates selected by the user */
DECLARE @Temp AS DATETIME
DECLARE @result table(WeekEndDate datetime)
SET @Temp = @Start + ((@WeekEnding - (DATEPART(w, @Start) - 1)) % 7) + CASE WHEN (@WeekEnding - (DATEPART(w, @Start) - 1))
< 0 THEN 7 ELSE 0 END

WHILE @Temp <= @End
BEGIN
INSERT INTO @result values(@Temp)
SET @Temp = @Temp + 7
END
