Try removing the DOCTYPE, to see if that's causing the trouble; and correct <books> on line 36 to </books>. With that change the document is valid, so if you're still getting a problem then its in the way you are invoking the schema processor.

On line 36 the line is </books>, <books> was a type for the forum.

You are correct DOCTYPE line is causing the problem. But my assignment I have to incuded both a schema and DTD validation. Is there away to include this line without the schema generating a error ?

Thanks for your help

Provided the document is valid both against the DTD and against the schema, it shouldn't be a problem. But invoking a parser to perform both validations becomes rather product-dependent, and I suspect the problem is related to the way you are running your chosen product.
