Zoho creator 5 api

Hi, 
I'm trying to add records using my web page contact form to zoho creator form.
using rest api:

<input type="hidden" name ="authtoken" value="*392c493bb37f3a82812c590ca4da2c98">
<input type="hidden" name ="scope" id="scope" value="creatorapi">
<input type="text" name="Name" value="Gary">
<input type="text" name="DOB" value="12-Jun-1980">
<input type="text" name="Address" value="USA">
<input type="text" name="Basic" value="10000">
<input type="text" name="Hobbies" value="Reading,Writing">


<input type="submit" value="Add Record">
</form>
using this sample and post http xml
and I get this response:
<?xml version="1.0" encoding="UTF-8" standalone="no"?><response><code>2945</code><message>XSS_DETECTED</message></response>

What is the problem?
