Ulises,

Assuming you are also displaying these new calculated results, you can just throw this code into the Form.Refresh(), then each LostFocus, just just do thisform.Refresh().

Bind your textboxes to form properties and you can simplify it even more:

sum importedd to thisform.xImpDD, costounit to thisform.xCostUnit ...

and you don't have to set each individual textbox.value

>I have this form with many calculated fields. Since the values of these fields are dependent upon values of several other fields, which can be modified at will by the user, I have the same lines of code repeated over and over in the Lostfocus event of these fields. So I have this code repeated about 7 or 8 times in my form:
>
>SUM importedd TO xImpDD
>THISFORM.text2.VALUE=xImpDD
