Programatically securing individual rows of data in Excel 2007 spreadsheet

I’ve received an odd request at work and I’m not sure how to even begin going about attacking it.  The user I’m trying to help has downloaded what is essentially a flat file then the adventure begins.
The following steps are what has been requested.  I’ve asked them to consider different options, but this is what they want and I’ve been unable to move them off of this specific request:
1)      Insert two blank rows between each row of data
2)      Format the blank rows where the font is italics and the color is red when inputs are added
3)      Protect the original rows (do not allow edits), but do allow inputs in the “new” blank rows that are input.  

The worksheet does not have to be password protected, only set up to not allow changes to the “original” data.

I’ve found this handy tidbit of code to insert the two blank rows, and then modified it to handle the formatting of the new columns, but that is as far as my skills with excel will allow me to go.

Sub Insert_2_Rows()
Dim i, nRows, firstRow
Application.ScreenUpdating = False
nRows = 2
firstRow = 1
i = firstRow + 1
While Not IsEmpty(Cells(i, "A"))
Rows(i & ":" & i + nRows - 1).Insert
Rows(i & ":" & i + nRows - 1).Select
    Selection.Font.Italic = True
    With Selection.Font
        .Color = -16776961
        .TintAndShade = 0
    End With

i = i + nRows + firstRow
Wend
End Sub

The assistance I need is with Step 3.  I tried protecting the sheet first, then running the macro to input the blank rows, but it gave me a 400 error.  I guess I’m looking for a way to protect the sheet programmatically, then to go in and “unlock” the rows where there is a blank value in column A (or vice versa, to lock only rows where column A is not blank).

FWIW, I’m working in Excel 2007.

Any help is obviously appreciated on this very unique request.

Probably you just want to unlock the new cells you're entering, and then protect the sheet afterward. To do this, add this line before the increment statement:
Selection.Locked = False

And then add this line after the while loop:
Activesheet.Protect

Also, don't forget to turn ScreenUpdating back on again, or you won't be able to do anything with the sheet after you run the script.

With a few other tweaks to code clarity, including the use of a Range object instead of selecting the rows to format, I suggest the following for your full script:
Sub Insert_2_Rows()
Dim i As Integer
Dim nRows As Integer
Dim firstRow As Integer
Dim rRows As Range

Application.ScreenUpdating = False
nRows = 2
firstRow = 1
i = firstRow + 1
While Not IsEmpty(Cells(i, "A"))
Rows(i & ":" & i + nRows - 1).Insert
Set rRows = Rows(i & ":" & i + nRows - 1)
With rRows.Font
    .Italic = True
    .Color = -16776961
    .TintAndShade = 0
End With
rRows.Locked = False

i = i + nRows + firstRow
Wend
ActiveSheet.Protect
Application.ScreenUpdating = True
End Sub

Once it's protected you would need to unprotect before making any changes. Can you unprotect then insert the rows and then protect again in your marco?

Activesheet.Unprotect
' Code to add blank row
ActiveSheet.Protect

Thanks for a very quick and helpful (and accurate) solution to this problem.  The only modification I have is to declare the variables as "Long" instead of "Integer" in the event that you have a large dataset of more than 32k records.  

I wasn't sure I was going to be able to figure this one out, but with the help of the EE community, another problem has been solved.  

Many Thanks,
MS
