Ms access calculated field not updating

How do you get Access to store the result of a calculation?

I am very new to the Acces and i am trying to calculate the Earned salary of the employee based on the no of Worked days.I have a database of some 500 Trusts who have donated to our Charity.I have a Form for each Trust, and on the Form I have a number of (currency) fields into which we input the amount donated by that Trust in Year X.You'll be able to ask any tech support questions, or chat with the community and help others.
