Excel 2007 : msgbox

hi, i need some help. i want to make a mgsbox with icon like exclamation icon but while using vbExclamation i can't use vbYesNO at the same time. is there some kind of symbol that i need to insert to make both work simultaneously?

there is my code


Sub message1()
reponse = MsgBox("Do you want to continue?" & Chr(10) & Time, vbExclamation, VbMsgBoxStyle = vbYesNo, "Question de vie ou de mort")
If reponse = 7 Then Exit Sub
response = MsgBox("Are you sure you want to continue?", vbYesNo, "Question de vie ou de mort")
If response = 7 Then Exit Sub
MsgBox "Then die!"
End Sub
