Accordion Menu, additional nested items

[magsuk]

1) Script Title: Accordion Menu

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...enu-glossy.htm and http://www.dynamicdrive.com/forums/s...ad.php?t=29611

3) Describe problem:
I've managed to configure the Accordion menu to incorporated nested lists as described on the forum, however I'm having problems positioning the +/- icons for the headers of the nested lists. I want them to be inline with the images in the main headers. I know my HTML and CSS are lengthy but I wanted different colour headers for each section. I attach a zip file containing the HTML (txt format, CSS and gifs).
I hope someone here can advise as I'm sure it's something relatively simple that I've overlooked!
Thanks in advance.
