Getting wrong values in User Defined Fields

Question

Hi Experts,
I am facing strange error while developing addon, my scenario is like below
1. Created .srf form which has 3 text box, 3rd text box does calculation(Subtraction) of other two.
2. For example 1st textbox has value 5000 and 2nd text box has 1000 but the value showing in 3rd textbox is 4999.
3. while debugging the code , values are coming properly in to variable. but after assigning it to the textbox values are not rite.
IMP NOTE:
      Same code is working fine in one machine (windows server 2008r,64-bit) but not working in other machine(windows server 2008r,64-bit)
same problem has been faced in windows 8 system also.
It would be very helpfull if anybody tells what might be the problem.
Thanks

Hi Parvatha,
Thanks for reply also sorry for confusion.,  here i made some changes in code and getting same error
  If pVal.EventType = SAPbouiCOM.BoEventTypes.et_LOST_FOCUS And pVal.ItemUID = "matItems" Then
                        oEdit1 = oForm.Items.Item("txtToWt").Specific
                        oMatrix = oForm.Items.Item("matItems").Specific
                        Dim sum As Double = 0.0
                        For k As Integer = 1 To oMatrix.VisualRowCount
                            oEdit = oMatrix.Columns.Item("colBndwt").Cells.Item(k).Specific
                            Dim qt As Double = oEdit.Value
                           sum = sum + qt                    // Here getting right value
                            oEdit1.Value = sum             // Not showing right value
                        Next
                    End If
NOTE: I've checked same source in 2 different machines it is working fine (earlier code also). only i am getting error in specific machine in client place.
if any issue with operating system? or any settings?
thanks
