Creating filter for SPAlert Programatically

Question

We are trying to create SPAlert programatically in Sharepoint 2007 portal, but we are encountering an issue while creating CAML query for eight parameters to filter. The e-mail is getting triggered for filter on one/two parameters.

Below is the CAML query for eight parameters, not sure what I am doing wrong.

    <Query>
    <Or>
      <Or>
       <Eq><FieldRef Name='consulting' /><ValueType='Text'>cbYes</Value></Eq>
       <Or>
         <Eq><FieldRef Name='consulting1' /><Value Type='Text'>cbNo</Value></Eq>
         <Or>
          <Eq><FieldRef Name='tags' /><Value Type='Text'>strTags</Value></Eq>
          <Eq><FieldRef Name='domain' /><Value Type='Text'>strDomain</Value></Eq>
         </Or>
      </Or>
     </Or>
      <Or>
       <Eq><FieldRef Name='consulting' /><ValueType='Text'>cbYes</Value></Eq>
     <Or>
      <Eq><FieldRef Name='stype' /><Value Type='Text'>strContentSubType</Value></Eq>
         <Or>
            <Eq><FieldRef Name='vertical' /><Value Type='Text'>strSubVertical</Value></Eq>
            <Eq><FieldRef Name='account' /><Value Type='Text'>strAccount</Value></Eq>
         </Or>
     </Or>          
    </Or>
</Or>
    </Query>
