appropriate category for my site

I have a question regarding my site.
My site is in 2 categories
1) http://dmoz.org/Business/Retail_Trade/Technology/Point_of_Sale/Hardware/Cash_Registers/
2)http://dmoz.org/Regional/Europe/United_Kingdom/Wales/Caerphilly_County_Borough/Business_and_Economy/

My site is called a&k cash registers because when we started we sold cash registers but now we also sell scales and point of sale systems hardware and software.
I think that the category http://dmoz.org/Business/Retail_Trade/Technology/Point_of_Sale/ is more appropriate for my site.
My question is
Do I use the “suggest URL” or “update listing”

Thanks

Aki

Please use update listing.

hi
when i try "update listing" i get
URL not found



The site http://www.akcashregisters.com is not listed in this category.

Please go back in your browser if you need to resubmit the form.

You have to use update listing in the category where your site currently resides.

http://dmoz.org/Business/Retail_Trade/Technology/Point_of_Sale/Hardware/Cash_Registers/

My assumption is that you are trying to do an update from the category where you wish it to move.

You are correct
thanks
