CopyingPasting contents from one sheet into another results in autofilling date

[ufgatorchick]

Hi,

DISCLAIMER: I'm completely green and have zero expertise at excel!

I've set up project management workbook that helps me keep track of my company's contracts by quarter. The Q3 spreadsheet is the first sheet in the workbook, and I set up some conditional formatting and macros to help automate dates, etc.

I'm now trying to move some rows from that sheet into a new sheet, but when I do, all the rows and columns convert to today's date. Once that happens, it won't let me undo it.

Any way to fix this?

Here is the code I have set up:
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Column = 9 Then Target.Offset(0, -1) = Date
If Target.Column = 7 Then Target.Offset(0, 1) = Date
If Target.Column = 1 Then Target.Offset(0, 2) = Date
If Target.Column = 3 Then Target.Offset(0, 9) = Date
End Sub

And here is the sort macro I have set up:
Columns("A:N").Select
ActiveWorkbook.Worksheets("2014Q3").Sort.SortFields.Clear
ActiveWorkbook.Worksheets("2014Q3").Sort.SortFields.Add(Range("L2:L10000"), _
xlSortOnFontColor, xlDescending, , xlSortNormal).SortOnValue.Color = RGB(118, _
147, 60)
ActiveWorkbook.Worksheets("2014Q3").Sort.SortFields.Add Key:=Range("N2:N10000") _
, SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:=xlSortNormal
ActiveWorkbook.Worksheets("2014Q3").Sort.SortFields.Add(Range("B2:B10000"), _
xlSortOnFontColor, xlDescending, , xlSortNormal).SortOnValue.Color = RGB(36, 64 _
, 98)
ActiveWorkbook.Worksheets("2014Q3").Sort.SortFields.Add Key:=Range("G2:G10000") _
, SortOn:=xlSortOnValues, Order:=xlAscending, CustomOrder:= _
"In Progress,Not Started,Internal Rev,External Rev,Deferred,With OC,Signed,Completed,Abandoned" _
, DataOption:=xlSortNormal
ActiveWorkbook.Worksheets("2014Q3").Sort.SortFields.Add Key:=Range("C2:C10000") _
, SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:=xlSortNormal
ActiveWorkbook.Worksheets("2014Q3").Sort.SortFields.Add Key:=Range("A2:A10000") _
, SortOn:=xlSortOnValues, Order:=xlAscending, CustomOrder:= _
"INC,BR,CC,BRI,CARE", DataOption:=xlSortNormal
With ActiveWorkbook.Worksheets("2014Q3").Sort
.SetRange Range("A1:N10000")
.Header = xlYes
.MatchCase = False
.Orientation = xlTopToBottom
.SortMethod = xlPinYin
.Apply
End With
End Sub

As an update, I just did some trial and error and isolated that the problem has to do with this code (when I removed the code and that brought the rows over, it worked):

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Column = 9 Then Target.Offset(0, -1) = Date
If Target.Column = 7 Then Target.Offset(0, 1) = Date
If Target.Column = 1 Then Target.Offset(0, 2) = Date
If Target.Column = 3 Then Target.Offset(0, 9) = Date
End Sub
