Hi everyone..
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
SUM costounit TO xCostoUnit
SUM costot TO xCosTot
SUM costoumn TO xCostoUMN
SUM costotmn TO xCosTotMN

THISFORM.text2.VALUE=xImpDD
THISFORM.text9.VALUE=xCostoUnit
THISFORM.text10.VALUE=xCosTot
THISFORM.text11.VALUE=xCostoUMN
THISFORM.text12.VALUE=xCosTotMN

and if I have to do modifications I have to do it in every instance. I know this is not good programming.

I think this can be done by writing a function once, but I'm lost regarding this subject.
Could somebody give me some general advise about how to write and make a function work, or maybe direct me towards an article that deals with this subject? VFP Help is not much help.
Thank you again for your time.
