The position of elements on the Product Information Page are controlled by sections of code in tpl_product_info_display.php .
The CORE file sits in:
includes/templates/template_default/templates/
When I look at your site's PAGE SOURCE, I see that you have not created a CUSTOM template, but have been making edits to the CLASSIC template. (This is a separate issue, but you should create your own csutom template...)
Anyway...
Get a COPY of tpl_product_info_display.php
Open that COPY for editing, using a PLAIN TEXT EDITOR.
The elements are "encased" in <!-- BOF --> and <!-- EOF --> comment tags.
All you need do is CUT and PASTE these elements above/below other elements.
In your case, find the section that relates to ATTRIBUTES, then CUT it from where it currently sits, and PASTE it higher up.
SAVE the file.
FTP the file to:
includes/templates/classic/templates/
You may also need to adjust CSS declarations to position this element more accurately.
