Help Needed with Dependencies in testng.xml

[Kumar]

I am unable to achieve dependency in testng.xml.

I want my second test "create new survey" should be dependent on first test "login".

I tried many things, but mostly I get error 

"DependencyMap::Method "CreateNewSurvey.CreateSurvey(java.util.Hashtable)[pri:0, instance:com.surveymanager.hybrid.testcases.CreateNewSurvey@4d9f6ce5]" depends on nonexistent group "LoginGroup""

Here is my testng.xml code given below:

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">

<suite name="Survey Manager Survey Creation Automation">

<test name="Logging into the Account:">

  <groups>

    <run>

      <include name="LoginGroup"/>

    </run>

  </groups>

  <classes>

    <class name="com.surveymanager.hybrid.testcases.LoginToAccount"/>

  </classes>

</test>

<test name="Creating a New Survey:">

  <groups>

    <run>

      <include name="CreateSurveyGroup"/>

     </run>

    <dependencies>

      <group name="CreateSurveyGroup" depends-on="LoginGroup" />

     </dependencies>

  </groups>

  <classes>

    <class name="com.surveymanager.hybrid.testcases.CreateNewSurvey"/>

  </classes>

</test>

</suite>

Please help.

Thanks,
