Hello,



I successfully created a fusion chart with an array using the ASP Class method which works beautifully on the testing server at my work. When I publish it to the live production server, however, I get the following error:



Microsoft VBScript runtime error '800a01f4'



Variable is undefined: 'Session'



.../onlinereports/fusioncharts_includes/FusionCharts_Gen.asp, line 209



Both servers are running IIS. Any ideas what may be causing this?

Thanks for your response.

I actually took your example that was included in fusion charts (Charts/ASPClass/ArrayExamples/Combination.asp) and ran it on our testing server without making any modifications - just copy and paste.  It ran perfectly. 

When I pushed it to the live server it gives the error:

Variable is undefined: 'Session'

/FusionCharts_Site/Code/ASPClass/Includes/FusionCharts_Gen.asp, line 209

Since I have made absolutely no changes the only thing that comes to mind is that there may be a setting that needs to be applied to the production server so that it works.  I'm trying to get a little more information before I call the IT group responsible for maintaing the live server.

Any thoughts on this?

Hi Webguy,
 
Thanks for your code.
 
Could you please make sure whether "Enable Session State" is checked (enable) in your IIS server or not.
 
For more information please refer to the attached image:
 
 
Hope this helps.

Hi Rahul,

Yes, the checkbox for 'Enable session state' is checked as well as 'Enable buffering' and 'Enable parent paths'.  Any other suggestions on what might cause this?

I figured it must be a setting issue since it works fine on the testing server.

Hi Webguy,



Could you please confirm once whether you have checked the above in your testing server or in "live production server"?

Good morning,



Thank you for the tip. I have sent the IT group that has access to the live server settings this request and am awaiting a reply.
