Hi Tom,

I would need staff or guest to edit only some fields. Not all. Is it possible?

The easiest way is to hide the fields with <div style="display:none;">
for example

<div style="display:none;">

....the fields you want to hide...


</div>

Even if the fields are hidden, they will be still posted. A problem is staff can still see the values if they see the source code of the page.
