Errors on If Statements

I'm trying to write code for henro8
http://www.excelforum.com/showthread.php?t=651731

and I get the following error with both nested if statements

Compile error: End if without block if

I tried with the Elseif and with separate if's but got the same error. What am I doing wrong?

Private Sub Worksheet_Change(ByVal Target As Range)
Dim RngCell As Range
Dim DrpDown As String

If Target.Column = 1 And Target.Row = 5 Then
    DrpDown = Target.Value
    Set RngCell = Cells(2, 5)
    
    If DrpDown = "$/square foot" Then
    With RngCell
        .NumberFormat = "$#,##0.00"
  
    ElseIf DrpDown = "%/construction cost" Then
    With RngCell
        .NumberFormat = "0.0%"
    End If
    
End If
End Sub

Thanks in advance!
