security token was missing

[chikuru]

Im getting this message from my custom plugin:

Your submission could not be processed because a security token was missing.

If this occurred unexpectedly, please inform the administrator and describe the action you performed before you received this error.

I have included these on the plugin codes but im still getting the error.
<input type="hidden" name="s" value="{vb:raw session.sessionhash}" />
<input type="hidden" name="securitytoken" value="{vb:raw bbuserinfo.securitytoken}" />

I also added
define('CSRF_PROTECTION', true);
Inside my plugin file..

It seems like security token is changing after the Paypal redirects back to my forums..

I think the whole code would need to be seen in order to debug it.

Here is the code of the form..
