Query Builder in Nintex (CAML Editor)

Hello,

I have two different list on same site. Wanted to look out for perticular value from one list to another (If it exists in another list).

Note: Lookup value is calculated field in main list.

Run throygh Query Builder (CAML editor)

<Query>
  <Lists>
    <List ID="{B75CF986-3323-424B-8301-E8F3439296D1}" />
  </Lists>
  <ViewFields>
    <FieldRef Name="DB_x0020_Email_x0020_ID" />
  </ViewFields>
  <Where>
    <Eq>
      <FieldRef Name="DB_x0020_Supp_x0020_Code"  />
      <Value Type="Text">{ItemProperty:Supp_x0020_Code}</Value>
    </Eq>
  </Where>
</Query>

There is no error but not getting ouput. It's not taking email ID.

Thank you,

Sonali
