[SOLVED] i need div or class name for menu 2 list items?

the default border styling on menu list items creates a double border along the left and right sides, so i thought to give my menu items a right border as a way to set them apart from one another.

i used this code: but it gave me a border on only the last item (one at the right end).

is there something else I should use to get a right border on each category 2 menu list item?

thanks in advance :-)
