Help me please with 1 question:

[kosti]

1. When filling a form I want to automate a field value as division of another field with a value in a query :
Ex. fields in the form:
Product, quantity , Cost
and fields in the query:
Product, Total cost


I want the field in the form: Cost = Query.totalCost/form.quantity

How to do that ?

Do it in your query and bind the results to a control on your form.
