Prompt for # of new rows, copy formulas and conditional formatting

Hi EF,

Per the subject, I have a workbook where people will continuously enter data at the rate of about 100 rows per day. The first and last columns (A and K) contain formulas and/or conditional formatting.

I found a macro that purports to do 80% of what I want:

Sub InsertRowsAndFillFormulas_caller()
  '-- this macro shows on Tools, Macro..., Macros (Alt+F8) dialog 
  Call InsertRowsAndFillFormulas
End Sub
 
Sub InsertRowsAndFillFormulas(Optional vRows As Long = 0)
' Documented:  http://www.mvps.org/dmcritchie/excel/insrtrow.htm
' Re: Insert Rows --   1997/09/24 Mark Hill <[email protected]>
   ' row selection based on active cell -- rev. 2000-09-02 David McRitchie
   Dim x as long 
   ActiveCell.EntireRow.Select  'So you do not have to preselect entire row
   If vRows = 0 Then
    vRows = Application.InputBox(prompt:= _
      "How many rows do you want to add?", Title:="Add Rows", _
      Default:=1, Type:=1) 'Default for 1 row, type 1 is number
    If vRows = False Then Exit Sub
   End If

   'if you just want to add cells and not entire rows
   'then delete ".EntireRow" in the following line

   'rev. 2001-01-17 Gary L. Brown, programming, Grouped sheets
   Dim sht As Worksheet, shts() As String, i As Long
   ReDim shts(1 To Worksheets.Application.ActiveWorkbook. _
       Windows(1).SelectedSheets.Count)
   i = 0
   For Each sht In _
       Application.ActiveWorkbook.Windows(1).SelectedSheets
    Sheets(sht.Name).Select
    i = i + 1
    shts(i) = sht.Name

    x = Sheets(sht.name).UsedRange.Rows.Count 'lastcell fixup

    Selection.Resize(rowsize:=2).Rows(2).EntireRow. _
     Resize(rowsize:=vRows).Insert Shift:=xlDown

    Selection.AutoFill Selection.Resize( _
     rowsize:=vRows + 1), xlFillDefault

    On Error Resume Next    'to handle no constants in range -- John McKee 2000/02/01
    ' to remove the non-formulas -- 1998/03/11 Bill Manville
    Selection.Offset(1).Resize(vRows).EntireRow. _
     SpecialCells(xlConstants).ClearContents
   Next sht
   Worksheets(shts).Select
End Sub

But I installed and ran it and it crashes my worksheet ("Not enough system resources to display completely"). This is being done on a pretty high-end computer (16GB RAM, i7 processor) so I doubt it couldn't handle such a task.

Also, this doesn't handle my conditional formatting requirement.

I've attached the worksheet in question (it's a binary) if anyone wants to take a stab at it or a different approach.
