Am trying to validate an xml schema file but is given me an error

[himansu]

I am using eclipse to edit and XML schema file. I have two files, file one and file two.file one seems to be ok but because file two is referencing file two (foreign key), I have this error. Though it can be seen from the code that file one has \[code\]namespace\[/code\]. I need come help.\[code\]src-resolve.4.1: Error resolving component 'pk_Top_200_Queries2'. It was detected that 'pk_Top_200_Queries2' has no namespace, but components with no target namespace are not referenceable from schema document 'file:///C:/java/workspace2/HomeWork2/Clicked_and_pos_12.xsd'. If 'pk_Top_200_Queries2' is intended to have a namespace, perhaps a prefix needs to be provided. If it is intended that 'pk_Top_200_Queries2' has no namespace, then an 'import' without a "namespace" attribute should be added to 'file:///C:/java/workspace2/HomeWork2/Clicked_and_pos_12.xsd'.\[/code\]file 1: name =Top_200_Queries2 and the schema is below\[code\]<?xml version="1.0" encoding="UTF-8"?><xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"targetNamespace="http://www.example.org/Top_200_Queries2"xmlns="http://www.example.org/Top_200_Queries2"elementFormDefault="qualified"><xsd:element name="T200Q"><xsd:complexType><xsd:sequence><xsd:element name="t200q" maxOccurs="200"><xsd:complexType><xsd:sequence><xsd:element name="qid" type="xsd:string" /><xsd:element name="query" type="xsd:string" /><xsd:element name="count" type="xsd:integer" /></xsd:sequence></xsd:complexType></xsd:element></xsd:sequence></xsd:complexType><xsd:key name="pk_qid"><xsd:selector xpath=".//t200q" /><xsd:field xpath="qid" /></xsd:key></xsd:element></xsd:schema>\[/code\]fiel 2 name= Clicked2.xsd\[code\]<?xml version="1.0" encoding="UTF-8"?><xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.example.org/Clicked2"xmlns="http://www.example.org/Clicked2" elementFormDefault="qualified"><xsd:element name = "Clicked2"><xsd:complexType><xsd:sequence><xsd:element name = "clicks" maxOccurs="unbounded"><xsd:complexType><xsd:sequence><xsd:element name="qid" type="xsd:string"/><xsd:element name="uid" type="xsd:integer"/></xsd:sequence></xsd:complexType></xsd:element></xsd:sequence></xsd:complexType><xsd:key name="pk_Clicked2"><xsd:selector xpath=".//clicks"/><xsd:field xpath="qid"/><xsd:field xpath="uid"/></xsd:key><xsd:keyref name="fk_contains_query" refer="pk_Top_200_Queries2"><xsd:selector xpath=".//clicks"/><xsd:field xpath="qid"/></xsd:keyref><xsd:keyref name="fk_contains_url" refer="pk_URL"><xsd:selector xpath=".//clicks"/><xsd:field xpath="uid"/></xsd:keyref></xsd:element></xsd:schema>\[/code\]both files are in the same package in eclipse.
