[Zope] ZClass manage_editProperties Question

I have created an advanced propertysheet editor, and am having trouble getting it to save the information. When I have the Form action="propertysheets/metadata", the data all saves correctly, but it redirects the page to the Zope standard propertysheet page (which I do not want it to do) When I create a DTML method, set the action equal to it, and then had the DTML Method run manage_editProperties with the REQUEST and redirect to the correct URL, but a value error occurs, stating that a empty value was received when an int was expected (even though no integers are in the form) Any ideas? - Alex
