My web.config transform doesn't work

I'm using a web.config transform to change a link in the production environment but when previewing it, the transformation doesn't happen..

Here is my code:

web.Test.config

  <configuration>
    <appSettings>
      <add key ="ELeg" value ="1"/>
    </appSettings>
  </configuration>
  <system.web>

web.Prod.config

  <configuration>
    <appSettings>
      <add key ="ELeg" value="10" xdt:Transform="SetAttributes" xdt:Locator="Match(key)"/>
    </appSettings>
  </configuration>

When previewing it on the prod and test envoirment, it doesnt add the appSetting.

Does anyone know what the problem is?

UPDATE

Here is my entire Test transform:

<?xml version="1.0" encoding="utf-8"?>

<!-- For more information on using web.config transformation visit http://go.microsoft.com/fwlink/?LinkId=125889 -->

<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
  <!--
    In the example below, the "SetAttributes" transform will change the value of 
    "connectionString" to use "ReleaseSQLServer" only when the "Match" locator 
    finds an attribute "name" that has a value of "MyDB".

    <connectionStrings>
      <add name="MyDB" 
        connectionString="Data Source=ReleaseSQLServer;Initial Catalog=MyReleaseDB;Integrated Security=True" 
        xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
    </connectionStrings>
  -->

  <configuration>
    <appSettings>
      <add key ="ELeg" value ="1" xdt:Transform="Insert" />
    </appSettings>
  </configuration>
  <system.web>
    <compilation xdt:Transform="RemoveAttributes(debug)" />
    <!--
      In the example below, the "Replace" transform will replace the entire 
      <customErrors> section of your web.config file.
      Note that because there is only one customErrors section under the 
      <system.web> node, there is no need to use the "xdt:Locator" attribute.

      <customErrors defaultRedirect="GenericError.htm"
        mode="RemoteOnly" xdt:Transform="Replace">
        <error statusCode="500" redirect="InternalError.htm"/>
      </customErrors>
    -->
  </system.web>
</configuration>

You don't have a key=10 to match on, you have a key=ELeg;

In other words, this (untested) transform should work better;

<?xml version="1.0"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
  <appSettings>
    <add key ="ELeg" value ="10" xdt:Transform="SetAttributes(value)" xdt:Locator="Match(key)"/>
  </appSettings>
</configuration>

Explanation of the transform attributes

xdt:Locator="Match(key)"               // Find elements with matching `key`.
xdt:Transform="SetAttributes(value)"   // Set the `value` attribute on the matches

EDIT: If you want to insert it and it does not even exist, then a plain xdt:Transform="Insert" is what you want;

<?xml version="1.0"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
  <appSettings>
    <add key ="ELeg" value ="10" xdt:Transform="Insert" />
  </appSettings>
</configuration>

Below will transform the value of the ELeg setting to 10:

<add xdt:Transform="Replace" xdt:Locator="Match(key)" key="ELeg" value="10" />
