Hello All, 

I am currently testing chat-up app from the appexchange in  a dev org. 

My requirement is to have chatter auto-post on the parent account once an opportunity is created. 

I have worked through the installation guide and now I am getting the following error when I try to create an opportunity. 

Apex trigger ChatterOpptyOnAccount caused an unexpected exception, contact your administrator: ChatterOpptyOnAccount: execution of AfterInsert caused by: System.SObjectException: Invalid field Account for Opportunity: Class.ChatterUpHelper.chatterUp: line 63, column 1

Please can you help me to resolve this issue? 

Regards

Bim
