Check if Directory Exist

I'm trying to use an if statement to save a file to the temp directory, if it exist, and save it to the network drive it a temp dorectory doesn't exist.

I think I'm close, but my searches in the forum didn't turn up anything to get me over the hump.

Here's what I've got:

If Exist "C:\Temp" Then
    ActiveWorkbook.SaveAs Filename:="C:\Temp\PO Response Tracking - Temp" & Format(Now, "hhmmss") & ".xls", _
        FileFormat:=xlNormal, Password:="", WriteResPassword:="", _
        ReadOnlyRecommended:=False, CreateBackup:=False
        GoTo Temp
    Else
    ActiveWorkbook.SaveAs Filename:="M:\PO Response Tracking - Temp" & Format(Now, "hhmmss") & ".xls", _
        FileFormat:=xlNormal, Password:="", WriteResPassword:="", _
        ReadOnlyRecommended:=False, CreateBackup:=False
    End If

Thanks in advance for any help you can offer.

Thanks, Kenneth. This worked:

If Dir("C:\Temp", vbDirectory) = "" Then
    ActiveWorkbook.SaveAs Filename:="M:\PO Response Tracking - Temp" & Format(Now, "hhmmss") & ".xls", _
        FileFormat:=xlNormal, Password:="", WriteResPassword:="", _
        ReadOnlyRecommended:=False, CreateBackup:=False
        GoTo Temp
    Else
    ActiveWorkbook.SaveAs Filename:="C:\Temp\PO Response Tracking - Temp" & Format(Now, "hhmmss") & ".xls", _
        FileFormat:=xlNormal, Password:="", WriteResPassword:="", _
        ReadOnlyRecommended:=False, CreateBackup:=False
    End If
