When I added Style dropdown...
 

it never shows other styles to select even though in the admin CP I set them to be selectable. They are selectable in the users option menu, but not in the dropdown style hack.

Any ideas?

Someone has to of chosen that scheme in their user options for it to show up in the drop-down style hack. Thats what I believe anyway.

I thought the whole dropdown box was to switch between schemes. Who cares who's using what template. :bored:

I ran into the exact same problem when trying to show both styles and users using the style (0 users = not shown).

I released a mod at vBT that avoids the problem by just not listing the number of users.

I've had the same problem too.
The query used by that hack isn't correct.

(btw: mine doesn't show users too)
