vertical centering

i’ve seen this on other threads, and this is what i’ve done:

i’m trying to center my relatively placed divs in a container of 428 px and width set to 100% in a table cell set to vertically align in the middle in a table.

the problem is that the other divs are not respecting the height of the container div in order for this to work.

i’d rather not use tables, but i really want this page vertically centered with left-right text flow. does someone mind seeing? I’ve taken out the table information.
