Microsoft Project 2007, Work Column doesn't add up

Question

I am creating a project file and I have a set of 4 tasks each with subtasks. In the "Work" column, I put the amount of work, in hours, for each subtask, but when it sums up at the task level it is always greater than the sum of the subtasks

For instance, I have task with 5 subtasks, one is 2 hours and the other 4 are 1 hour each. But when it adds it up it says 8 hours. I dont understand what I am doing wrong here, I just want to keep track of the hours used on the project so we can compare it to the baseline at the end.

Here is the screenshot:

Answer 1

Yes that is correct. The parent task should not have a resource assigned to it. Only the sub tasks should have a resource assigned.

Answer 2

I found the issue, it seems that adding myself to the Tasks also added the amount of cumulative hours for that task. So I removed myself from the tasks and only added to the subtasks and everything adds up correctly.
