Automatically insert a formula when I enter data using a form to a database

[wattsup]

Hi,

I have a database and have made a form that can be used to fill it in. However, some of the columns of my database use formula's to create their entries but when I press ok on my form it inserts my data on a new line as intended but the formula does not automatically be inserted to the new line. How can I make it do this?

Thank you in advance
