Help with textbox Function

i want to check if the textbox is 9 digit long and isnumeric- once its check then i can save, but if not it highlights and set focus, i got it right doing it the regular way, but once i write my function it does not work. im not sure what i did wrong. here is what i got
Public Function save(ByVal textbox As TextBox) As TextBox
If Not IsNumeric(textbox) Or Not textbox.Text.Length = 9 Then
MsgBox("can not be save")
textbox.BackColor = Color.red
textbox.SelectAll()
textbox.Focus()
ElseIf IsNumeric(textbox) And textbox.Text.Length = 9 Then
MsgBox("phone must be 10 digits")
End If
Return textbox
