Hello, I am trying to adapt a macro from Ron DeBruins website to email an array of sheets but it is failing when it is trying to determine which sheets to send. The error message says "Run-time error '9': Subscript out of range" A second question I have is how do I change this to only email the visible sheets?

This is the line it is failing on:
.Sheets(Array("Supplier Instruction Sheet", "R&D Request-Protein", "Sample Analysis", "Sample Arrival Summary", "Protein R&D Formula Pricing", "Protein-Prelim Spec")).Copy
The whole macro:

Sub Prot_Mail_Sheets_Array()

    Dim FileExtStr As String
    Dim FileFormatNum As Long
    Dim Sourcewb As Workbook
