[Zope] Access help

[Todd Loomis]

Can anybody help, I'm trying to make a drop-down list of folders a user has 
access to add files to. However I only way I can get it to work is give 
each person access to contents permissions on all folders. So far it won't 
let the actually in the folder but it shows it to them. Here's my code how 
can I keep the folders the can't upload too for the list:

<select name="folder">
<option value="" selected>Select from list</option>
<dtml-with folders>
	<dtml-if expr="_.SecurityCheckPermission('Add Documents, Images, and 
Files', this())">
		<dtml-in expr="objectValues('Folder')">
			<option value="<dtml-var id>"><dtml-var title></option>
		</dtml-in>
</select>
	</dtml-if>
</dtml-with>

Thanks,
Todd
