I've spent a couple of hours on this now and have read through all 22 pages looking for what I have done wrong

I have 1.3.7 and trying to install this module version 1.4.1

I believe I have followed the directions correctly - but when I go to
http://www.kwmagic.com/index.php?main_page=pricelist

I get this error:

Fatal error: Call to undefined function: display_price_nosymbol() in /home/kwmagicc/public_html/includes/modules/pages/pricelist/header_php.php on line 574


any insight appreciated

thanks
