HI Joao,

I do it this way. I create several form properties to store interm values and then add a method to the form with code like this:
LOCAL slnCurArea,slnRecNo

DO CASE
CASE EOF('Invoice')
ThisForm.nsubtotal = 0
ThisForm.ntax =0
ThisForm.ntotal = 0
CASE EOF('invoice_items')
ThisForm.nsubtotal = 0
ThisForm.ntax = 0
ThisForm.ntotal = 0
OTHERWISE
slnCurArea = SELECT()
SELECT invoice_items
slnRecNo = RECNO()

SUM invoice_items.price*invoice_items.qty ;
FOR invoice_items.invoice_number = invoice.invoice_nu ;
TO ThisForm.nsubtotal

SUM EVAL(thisform.pgfChild.page1.grdChild.Column7.controlsource);
FOR invoice_items.invoice_number = invoice.invoice_nu ;
TO ThisForm.nTax

GOTO slnRecNo
SELECT (slnCurArea)
ThisForm.ntotal = ThisForm.nsubtotal+ThisForm.ntax

ENDCASE

ThisForm.pgfChild.page1.txtsubtotal.Refresh()
ThisForm.pgfChild.page1.txttax.Refresh()
ThisForm.pgfChild.Page1.txttotal.Refresh()

refreshing the form then updates the totals. Don't know if this is the proper way to do it but it works, well.
Also note some of the code above is dependent on the form of mine I pulled it out of so mods will need to be made to work for you. It's only provided as a guide to show the idea
