Deadline approaching soon… HELP!!

I have three fields

Life Skills Credits Earned Total

I need to enter a number in the Life Skills Credits. The Earned field should continue to add what I enter in the Life Skills Credits, but I need the life Skills Credits to revert back to 0 (zero)

I hope I explain this right…..

When do you need the life Skills Credit to revert back to 0

After I enter a number.

Earned must keep the calculation
That is entered in the Life Skill Credits

Example:
If I enter 10 in the Life Skill Credits.
The total in the Earned field should be 10.
Now When I have to enter a 5 for Life Skill Credits
The total should now be 15


Please Help
