Tracking - Work v Actual Work - why is it not working?

[Beth]

Hi, Can anyone help me - Microsoft Project is causing me grief!

I am trying to plan and track the workload of a number of small
projects. I want to run the project using hours so that planned time
can be compared to subsequent timesheet information.

Each project that comes in is broken down into phases - 00 - 10
although not all phases apply to each project. So, for example when I
am planning time I use the task or resource view:
M T W
- Fred Smith (Resource) Work 8 8 8
Act. Work 8 8 8
Project 1 Work
Act. Work
Phase 00a Work(predicted @ start) 8 8 8
Act Work 4
Phase 00b Work
Act. Work 2 4
Phase 05c Work
Act Work 2 8 4

The above is how it should look - however when I go to enter the
hours in actual time it automatically adds the same amount to the work
box knocking the total time for the day over 8 hours.

How can I stop this happening? I have saved my baseline and turned off
all the calculation functions in tools/options. I am using Project
2002.

Thanks in advance Beth
