ASPX Page - Script Error: Expected ';'

I am using the C# Exam Cram for 70-315, and I have the following code:

<%@ Page Language=“C#” %>

Fahrenheit to Celsius Conversion Chart

<% for (double f=50.0; f<=100.0; f++) { // Sends formatted output to HTTP response Response.Output.Write( "", f, ToCelsius(f)); } %>
° Fahrenheit° Celsius
{0}" + "{1:f}

When I run it from Visual Studio (View in Browser) I get the following error message:

Line: 5
Char: 10
Error: Expected ‘;’
Code: 0
URL: http://localhost/ExamCram/315C02/Example2_1.aspx
