[Plugin: Content Types] Query in a 'Select" type field : get_posts parameters

Hey out there!

I’ve set up 2 content types : “Catalog” and “Artists”.

In the “Catalog” content type, i’m trying to pull a list of the “Artists” content type in a Select-type field.

If I use post_type=artists in the query field, it gets the right content type, and returns a list of the content type Titles.

What I would like to get is a list of “Name” : “Name” being a field created for the Artists content type.

I tried post_type=artists&meta_key=name to no avail.

In short: what parameters do I have to use to pull a meta_key in a select field?

Thanks in advance! (and sorry for my bad english).
