list more than one custom post field

I have a custom post called ‘talks’ that has several custom fields, including ‘Speaker’ and ‘Date’. I’d like to show various thing in the list category posts list, including both theses custom fields.

I tried:

[catlist post_type=talk  class=video-list order=asc pagination=yes numberposts=15 thumbnail=yes thumbnail_size=medium template=default  customfield_display=Date  customfield_display=Speaker]

but that only displayed the date field,

[catlist post_type=talk  class=video-list order=asc pagination=yes numberposts=15 thumbnail=yes thumbnail_size=medium template=default  customfield_display=Speaker,Date]

that does display both the Speaker and the Date fields but on the same line with not one space between them.

Is there a way to display more than one custom field on separate lines?

Thanks
