expanded text css

[Orange]

I'm really hoping someone here can help with this. I went through A LOT of trouble to finally get wp e-commerce working, customized the look and all....and now the "more details" does work in two ways:

1) the expanded text doesn't push the rest of the page down, it just overlaps what's there, which is unreadable.

2) when the expanded text is expanded, the arrow doesn't change to an upward position for "collapsing" the text. Yes, I did change the images for expand and collapse.

I really appreciate the help! I know I moved things around to make it look nicer, but I'm not sure what I did to the expanded text area to make it not work....

Thanks!
