I'm trying to read a macro that will sum up corresponding values associated with a series of dates. IE- Jan. 1st will have 20 rows, with corresponding entries of 20, 50, 80, in respective columns. I want a macro that will sum all of these entries, and once all of the Jan. 1st entries are summed, then it will move on to Jan. 2nd, and sum all of those entries. The code that I have written so far gives me a loop without do error.
Private Sub CommandButton1_Click() Dim dateCheck As String Dim shipDay As Date Dim L As Integer Dim i As Integer Dim S As Integer Dim search As String Dim usaTotal As Long Dim usaCredit As Long Dim usaDebit As Long L = 10 i = 3 dateCheck = InputBox("What Date is Ship Day 1?", "Ship Day Entry") If IsDate(dateCheck) Then shipDay = DateValue(dateCheck) _ Else: MsgBox ("Invalid Date") ' Prompts user for ship day 1, and checks if actual date While Not Worksheets("Sheet1").Cells(i, 8).Value = "" ' Runs until all cell rows are accounted for For S = 0 To 29 shipDay = shipDay + S Do Until shipDay <> Worksheets("Sheet1").Cells(i, 8).Value ' Execute until new date search = Worksheets("sheet1").Cells(i, 12).Value ' Variable to use InStr to check for "CAN" If (((shipDay = Worksheets("Sheet1").Cells(i, 8).Value) And _ InStr(1, search, "CAN", vbBinaryCompare) = 0) _ And (Worksheets("Sheet1").Cells(i, 6).Text = "Invoice")) Then 'Check that date matches, and that it isn't Canada, and that order is an invoice usaDebit = Worksheets("Sheet1").Cells(i, 22).Value ' Account for Debits usaCredit = Worksheets("Sheet1").Cells(i, 24).Value ' Account for Credits usaTotal = usaTotal + usaCredit - usaDebit ' Calculate contribution i = i + 1 End If Loop MsgBox (usaTotal) Next S Worksheets("JUNE Canada").Cells(i, 22).Value = usaTotal MsgBox (usaTotal) ' Need code here that will input final usaTotal into respective space MsgBox (usaTotal) Wend ' End of Initial "while not" End Sub
