That means that you have an error in the way you put the connection string in your web.config. Please post the relevant section of the web.config in here. The connection string should have the name "ConnectionString" like in the example below:

    <connectionStrings>
        <add name="ConnectionString" connectionString="yourConnectionString" providerName="System.Data.SqlClient" />
    </connectionStrings>

Update: as I said above, looking at your web.config I can see that you have to change the name of your connection string from "trdagingcallsConnectionString2" to "ConnectionString"
