Help with calculation

### Post

I need to create a calculation and have done so before but cannot figure out how to do so for what I am needing. I'm creating a database to keep up with vacation and sick leave time. When the vacation/sick leave form is filled out and the number of hours is entered, I want it to subtract from the amount I currently have and give me the updated amount. I also want it to add the vacation (11 hrs) and sick time (8 hrs) that I get on the first of each month. (Ex: If I am taking 8 hours of vacation and have a total of 50, I want it to subtract 8 from 50 and give me 42. Then on the first of the month, I want it to add back 11 hours for a total of 53 hours). Any help would be greatly appreciated.

You'll need to describe the fields, tables and relationships you have in much more detail before we can offer a suggestion consistent with what you currently have in place.
