Dreamweaver: Please use only numeric entires for values

Hello,

I use Dreamweaver CS4 (Master Collection) and try desperately to fix a problem related to displaying accurately french accents (é, è, à, ...) in the charts provided in POWERSTORE 2 from WEBASSIST (Yes, I'm localizing the US version into a FRENCH edition). These accented caracters are not dispalyed at all if I enter them as is (é, è, à, a.s.o.) into the charts using the XML Editor (latest edition of Dynamic WebCharts in use !!). Even if I use the HTML "é" a.s.o. these caracters are displayed as "?" marks instead !

I guess that the WA people should collaborate with both teams (POWERSTORE 2 and DYNAMIC WEBCHARTS) and let the communitiy know what to do to get rid of this frustrating problem. It may be a minor thing but I don't see what !

Furthermore using the EDIT IN WIZARD button while clicking on the <param name="movie" value="../DynamicWebCharts/open-flash-chart.swf?data=../DynamicWebCharts/Data/Products_Chart_dataparser1.php?<?php echo (isset($_SERVER['QUERY_STRING'])?"GET=".str_replace("&","§",$_SERVER['QUERY_STRING']):'');?>" /> in the file Products_Chart.php (in POWERSTORE 2, of course), Dreamweaver signals the message mentioned in the title of this posted thread (Dreamweaver: Please use only numeric entires for value). This popup message makes your life tricky while trying to edit the charts.

Please help me to understand what is going wrong. Maybe I did something wrong !

Many thanks
