I am creating a report and have a field in my database called "Duration" which is represented in time format. I am trying to calculate the total duration by adding the durations together using "[Sum(Duration)]". I keep however getting "#ERROR" when I do this.

If anyone could help me out I would be very grateful!

When you are trying to get sum of a TimeFormat, you should sum the minutes.
Try executing this query in your query window

SQL

Declare @TempTable Table(TimeValue VarChar(20))


Insert Into @TempTable Values('12:00 PM')
Insert Into @TempTable Values('1:00 PM')
Insert Into @TempTable Values('10:00 AM')


Select Sum(DateDiff(Minute, 0, TimeValue)) As TotalDuration
       From   @TempTable
