How to avoid message about leaving data in clipboard?

I am creating a program that opens an excel file on the network, copies data from a worksheet from that workbook on to ThisWorkbook and then closes the workbook on the network.
Everything seems to work fine except that when I close the workbook on the network, it displays a message asking if I want to leave the data on the clipboard for future use.

What code do I need to avoid getting this message? I would like to close the workbook without leaving anything in the clipboard, but I don't want the user to see this message.

Here's the code that opens the workbook and copies data.

Workbook.Activate FileName 
             Worksheets("Input").Activate
             Range("C1:F103").Copy
            
ThisWorkbook.Activate
Worksheets("PASTE TIP SHEET HERE").Select
Range("C1:F103").Select

Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
        :=False, Transpose:=False


Workbooks(FileName).Close SaveChanges:=False

I am sure there is probably a more efficient way to do this and avoid getting the message.

Thanks for any help I can get.
