Sending an email from Excel to multiple email addresses

I am using the following code and it works great the only problem is that when I have more then one email address in the same cell it will not send the email. Even if I seperate it with a semicolon. It work fine if I have just one email address in the email field. How can I get it to send the same info to different email addresses.

Sub Email2()

    Dim rng As Range
    Dim Ash As Worksheet
    Dim Cws As Worksheet
    Dim Rcount As Long
    Dim Rnum As Long
    Dim FilterRange As Range
    Dim FieldNum As Integer
    Dim NewWB As Workbook
    Dim TempFilePath As String
    Dim TempFileName As String
    Dim FileExtStr As String
    Dim FileFormatNum As Long
