Validation Problems

[Guest whack]

Hi there,I've done the schema tutorial on the site and followed instructions yet I'm having problems with my XML doc validation. I'm at my wits end to find what the problem is as this should be "bread and butter" stuff. I've created both a schema and an xml doc which are below and I've been trying to validate them using this site: http://apps.gotdotnet.com/xmltools/xsdvalidator/default.aspx . Alone, the schema validates fine (as well as on the W3C XSV validator) but trying to validate the XML doc is giving me errors such as:"Could not find schema information for the element 'http://www.stis.com:query'"where query is my root node. But it goes on to give this error for every element in my xml doc. Obviously it is do with the namespaces or the schemaLocation but I can't see what the problem is as the targetNameSpace and the xmlns/schemaLocation are the same in both docs and both are in the same directory....It is more than likely something extremely simple that I am overlooking but at this stage I'm code blind :-(Any help or tips would be greatly appreciated.....Thanks,Pat :-)query.xml
