Sorry for bodering

I did what you said and didn´t work

I added a textbox named tbTestData and then added the property to the form TestData. ControlSource for tbTestData is Thisform.TestData

The values are located in column17 named colTotal

In the click property of a buttom name command1 i wrote this:

select cruzada (cursor1)
sum thisform.Pageframe1.Page2.Grid1.colTotal to thisform.TestData
thisform.Pageframe1.Page2.tbTestData.refresh

the result sais that is not a numeric expression and returns an object.

what i´m doing wrong?

I Promise this is the last question

Thanks
