Caluculate with forms

[sofie]

I would like to calculate with a form.
In my current form I fill in several fields. When evertything is filled in, I click oon a button. This button have to calculate the eprice. The price depends on the fields who were filled in.
In an other form, I mention wich field is wich price.
Do I have to use Exell? Or is it possible to do it in access?
Who can help me?

You don't need excel. just write down
the arithmetical calculation with the relevant fields:
=[FieldName1] + [FieldName2] * [FieldName3]
