Conditional links

I need to creat a shipping list from an order list

order list
column a1:a25-- furniture items
next to some of these furniture items is a column with an "x" or ""

on my shipping list I would like to list all the items from column a1:a25 that have an "x" next to them. I can create the formula for 1 cell but I can not figure out how to list all the items.

thanks in adavance for your help,
