Thank you Julie
I'm running Microsoft Project Professional 2010 - Service pack 2



I've tried several columns where I can put in value/cost and every time the numbers change. At first I thought is was because i had linked the tasks together (predecessors) So I started from scratch but all the same. It's odd that some numbers change while others do not. I also tried to add value to the number where the value was subtracted but then a new number would appear. There is no logic to these changing of value. Some numbers is added with 1, 2, 4 add 4 and other subtracted wit the same numbers.

Does the error occur in a new project file? I have never seen Project randomly add or subtract values and I cannot reproduce entering values directly into the Cost field in Project 2010 SP-2. Linking should have no effect on costs.

Are you seeing the changed values in the Visual Reports or in the native project file? If you look at the Task Usage view and add Cost to the right side, does all appear normally?
