ul li bullets

hi,
i’m really happy with the plug but just have some nagging problem i seem unable to fix.

elsewhere in the website i have lists with disk bullets and i want to keep it that way.
however, gridster also puts a disk before every item in the grid. i tried things like:

#gridster .entry ul li{ list-style-type: none; list-style: none;}
#gridster ul li{ list-style-type: none; list-style: none;}

but it ain’t working.

please help, thanks!
