Problem with XML to add a record to a table I have created in Creator

Can you please tell me if there is anything obviously wrong wit the xml below.

<input type="hidden" name ="authtoken" value="**********************************">

<input type="hidden" name ="scope" id="scope" value="creatorapi">

<textarea name="XMLString" >

</textarea>

<input type="hidden" name="peterstanesby" value="sampleapps">

<input type="submit" value="Add Record">

I have changed it a number of times but it always comes up with a 500 Internal Server Error.

Thanks for your help.
