erro na pág (<customErrors>)

[marcelonhenhe 0]

um código que axei na net está dando o seguinte erro:

 

Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

<!-- Web.Config Configuration File -->

<configuration>
   <system.web>
       <customErrors mode="Off"/>
   </system.web>
</configuration>


Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

<!-- Web.Config Configuration File -->

<configuration>
   <system.web>
       <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
   </system.web>
</configuration>

 

 

 

mas se Add a tag <customErrors> que pede ocorre um erro na pag, é o lugar que estou colocando que está errado, se sim, onde no código eu deveria colocar... o codigo da pag está abaixo:

[quintelab 91]

Mas o erro ocorre não é por causa da tag ou do web.config. A primeira mensagem é uma mensagem padrão de erro do asp.net.

Debugue a aplicaçao para ver o que é o erro.
