ok, so i still dont get it. 
  
im trying to do a Drill down chart but i get the "no data to display"  error because the second chart has to be a simple chart and im working  with a multichart. 
  
si have this code: 
  
" 
Grafico1.Text =  FusionCharts.RenderChart("FusionCharts/StackedColumn3D.swf", "",  MotorGrafic.xmlGrafico, "myNext", "600", "300", True, True, True) 
" 
on the code behind where i render the chart but i dont know how to spesify that i want to use another SWF for my second chart. 
the XML Data is given in the string "MotorGrafic.xmlGrafico" wich is generated in another class. 
  
i tryed to understand the documentation that i think says what i have to  do. but i simply dont undestand it. mind to explain it to me? 
  
the documentation i was lookin was this one: http://www.fusioncha.../?CS_Drill.html 
  
  
thank you so much for this.
