Does any one trouble shoot css ul ol?

[SOcRatEs]

Can you spot what I did wrong with nesting OL with UL?
Hover buttons got wacked when I started nesting OL.
I now have "1." on leftside of buttons
Website
My OL listing is correct:
1.
2.
--2.1
----2.1.1
3.
4.
--4.1
I think maybe triple nesting may have hosed it.
Thank you to anyone who can help!!

you discribing the hover state change to lighter color
if so all works here (firefox)
may try using full url's
as some browsers don't convert the same
should check for dual compliance
add a browser check to css
my header for all pages contant only the css link no css code

m7l.com/catalog css with php

I think you are right. Thank you!
I'm brand new to css, still learning how to construct style sheet, then call it from body of html via tag.

I'm still using the nested ol:

<style type="text/css">
body {
background-image:
url('images/bg22.jpg');
background-attachment: fixed;
}
OL { list-style: decimal }

OL OL { list-style: lower-alpha }

OL OL OL { list-style: lower-roman }
</style>
I don't know how to convert this to my style sheet. but I'm getting there.

My new layout.css

Install/use Firefox and also get the Firefox extension "Web Developer". It does wonders when checking out your new web pages. It includes CSS as well.

You and a few others here got me using FF months ago.
I did not know about the Web Developer part tho thank you!

BTW
How goes the move?

edit. WOW!
I've been using view source but this is incredilble!!!

 

[RealBlackStuff]

Everyone always likes that Web Developer! I particularly like the Outline function.

As to the move, our house only went on the market last Friday, first viewers coming in on Monday already. We have de-cluttered and repainted most of the interior, and use temporary storage for the de-cluttered stuff.
We have several quotations in from movers. Based on that we sold some large furniture, so we can limit it all to a 20-ft. container.
Right now we are knackered from all the cleaning/painting etc.
