Hi,
Its not using the connection string you added. Even though ASP.NET 2.0 came out with the <connectionStrings section, we don't use it because it has disadvantages compared to just using <appSettings section.
If you look in <appSettings section of web.config, the connection string is already there, you just need to edit it:
<add key="FirebirdConnectionString" value="Data Source=localhost;Server Type=0;Port Number=3050;Database=C:\Users\JoeAudette\devprojects\mojoportal\mojoportal.fdb;Dialect=3;Charset=UTF8;Pooling=True;Min Pool Size=0;Max Pool Size=200;Connection Timeout=10;Connection Lifetime=60;Fetch Size=200;User Id=SYSDBA;Password=masterkey" />
But really what you should do is create a user.config file and put your connection string there, that way you have no svn conflict when you get updates because user.config is not under source control and it overrides what is in Web.config <appSettings
See my article on Web.config here for more info:

Hope it helps,
