2 questions, copying data from sheet to sheet and assigning macro
 

I need a bit of help. I'm tying to copy a range of cells from one sheet in
my workbook and add it to sheet 2 in the same workbook at the bottom. I'm
using this as a database for simplicity's sake.

2. after assigning this macro to a button, can I password protect the button
itself to prevent what I call IDIOT-isms.... this sheet will be shared by
quite a few people but only 2 may update using the afore-mentioned macro.
here is what i have so far.... but it only copies to a set range and does not
append.

Range("A2:K2").Select
Selection.Copy
Sheets("sheet2").Select
Range("A3509:K3509").Select
ActiveSheet.Paste
Selection.Interior.ColorIndex = xlNone
Sheets("Sheet1").Select
Range("K2:A2").Select
ActiveCell.FormulaR1C1 = ""
