move advert 4 position

its the white area behind advert 1

i think because we moved advert 4 +150px that also included the shadow

the bit at the bottom that i mentioned earlier i has fixed - when i add the graphic the code puts a <p> tag on to it - if i deete them and save it it appears in the correct position

You need to add this to layout.css:

.upper .module_padding {
width: 570px;
}

but first module requires 600px so you must decrease it size or size of right module, or increase template width.
