Excel Error when trying to add attachment to email

Hey guys amd gals, I am getting an error when trying to send an automated email with an attachement. Without the attachment it works just fine. I've done this before, with only minor changes to the code and it worked just fine, so I am at a loss now.

    Dim sAtt1 As String: sAtt1 = "O:\CSO\Repair Management-Service Partner Data\DealerNotification\dealerEmail\unitsPerDealer\202960.xlsx"
    Dim sAtt2 As String: sAtt2 = "O:\CSO\Repair Management-Service Partner Data\DealerNotification\dealerEmail\nationalAccountSoldUnits.xlsx"
    Dim sAtt3 As String: sAtt3 = "O:\CSO\Repair Management-Service Partner Data\DealerNotification\dealerEmail\warrantyExtensionLetter.pdf"
    
    Dim OutApp As Object
    Dim outMail As Object
    
    With Application
        .EnableEvents = False
        .ScreenUpdating = False
    End With

    Set OutApp = CreateObject("Outlook.Application")
    Set outMail = OutApp.CreateItem(0)
    
    With outMail
        .To = "[email protected]"
        .Subject = "Warranty Extension Program Dealer Notification"
        .Body = sBody
        .Attachments.Add = sAtt3
        .Attachments.Add = sAtt2
        .Attahcments.Add = sAtt3
        .Send
        
    End With

Here is my error:

When I debug, it highlights the first .Attachements.add

However, if I comment out the first two attachments, and only try the third, it changes the error code to a 438.

TIA for the help!

Wow...

I know better. Thank you, TMS.

Can I use the "I am on pain killers and having surgery tomorrow" excuse?
