The code would help:
$(document).ready(function() { var thisUserAccount = $().SPServices.SPGetCurrentUser({ fieldName: "Name",debug: false}); $().SPServices.SPFilterDropdown({ relationshipList: "{BC8B39D8-2567-4EE9-B73A-2598C18BA823}", relationshipListColumn: "Subscription_x0020_E_x002d_Mail", columnName: "Subscribers", listName: "{2996F581-6CAE-466A-BD2C-C9F4B5465ABD}", noneText: "(None)", CAMLQuery: "<Eq><FieldRef Name='Person2'/><Value Type='User'>"+thisUserAccount+"</Value></Eq>", completefunc: null, debug: true }); }); </script>
