Hello, 

This is my first attempt to add a new opportunity from Excel using the Excel Connector.  I get the following error: 

Salesforce: Create()

invalid Range, missing data type, or other error,

type is: Opportunity

The current field definition for "CreatedById" require a value to be set.

For my test, I copied a row that I downloaded using the Connector, changed the name and put new in the Opportunity ID.

My goal for this is to add closed/won opportunities into salesforce that did not originate in saleforce so that we can see all activity.

Thanks for your help.
