web.config file error

I am getting "Section must only appear once per config file" error... I need an extra set of eyes for this.  I have no idea what is appearing twice...

Can someone tell me?   Thanks..

Here is the web.config.

Maybe this:

<httpHandlers>
    <add path="ChartImg.axd" verb="GET,HEAD" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false" />
  </httpHandlers>
  <handlers>
    <add name="ChartImageHandler" preCondition="integratedMode" verb="GET,HEAD" path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
  </handlers>

Hi there,

The section  <httpHandlers> goes under <system.web>. I'm not sure about <handlers>, as it seems to be a custom element, but I guess that should be put under system.web as well.

  </httpHandlers>
This portion should be put between <System.web></System.Web>
and
<handlers>
    <add name="ChartImageHandler" preCondition="integratedMode" verb="GET,HEAD" path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
  </handlers>

This would come between the section  
<system.webServer>   </system.webServer>

 Rewrite the web.config with the above changes and u will get the result
Hope this helps

Why do you need <handlers> section? Don't you need only <httphandlers> ??

I am going off what the Microsoft guys said in their little bit of documentation about MSCharts....

I got this to work.  For some reason Visual Studio 2008 was (I think) corrupting the web.config file when I would drag and drop a MSChart onto my webpage.  

SO what I did was download the samples for MSCharts, I copy the sample web.config into my project, and everything started working.

I am still going to give out the points because you guys helped place the entries into the right area in the web.config file.
