How do I refer to result in order form, from customer form?

[Mehdi]

Hi my name is Mehdi,
my question is how to get the result of the calculation that already has
done in orders form, like Order Total, into the another form like order by
customers subform. Or generally refer to any calculation result in any form
from other forms?

Your help is appreiciated

You can use a text box with a control source of:
=Forms!YourFormName!YourTextBoxName
