RSS & Google Base - Problem

Hi, can anybody help with following :
1. I bought module for RSS - it works ok but for Google base I always got report :

Invalid attribute: price (50 errors)
The value you provided for the attribute is invalid.
Examples: Examples:
Item Nr. Line Nr.
5 126
13 364
26 701
37 1,001
39 1,059

link is : http://www.buythebest.eu/rss.php

2. On the Categories Pages (v1.4.8b) products are everywhere shown default - sort by Model number of products. How can I make to be shown random ( On the homepage I did it as was described in the forum and it works well but for this case I can´t find anything).

Thanks in advance.

What settings do you have for price? Looks like 0005, 0024, etc
The googlebase price field shows:
http://base.google.com/support/bin/answ ... swer=78170

So I assume it expects a decimal

Price in OC data form I enter as : for example 1.5900
