[Product-Developers] Re: custom at edit form?

I tried following Tom's instructions and failed. Specifically, I simply 
copied base_edit.cpt to my product's skins folder and renamed it 
'servicepage_edit.pt'. I then changed the GS profile for my type to replace:

<alias from="edit" to="atct_edit" />

with:

<alias from="edit" to="servicepage_edit" />

Note that I did not make any edits to the copied and renamed template. 
When I attempt to add an object, I get (hang on!):

Remember, the template is just the renamed and moved template from Plone 
3.0.6. Ideas?

Thanks!
