I am working on the Multiple joins. The instructions says to : Write, run, and save a query that joins individuals to their sales accounts and filters for individuals with annual revenue values greater than 500000000Copy:

• Use the individual object (ssot__individual__dlmCopy, alias individualCopy)
• Join the account object (ssot__Account__dlmCopy, alias accountCopy) to the individual object using the individual ID (individual.ssot__PrimaryAccountId__cCopy) and the account ID (account.ssot__Id__cCopy).
• Select the individual's first name (ssot__FirstName__cCopy) to easily identify them.
• Filter for accounts with revenue (ssot__AnnualRevenueAmount__c) values over 500000000Copy

My query is:   

SELECT ssot__FirstName__c AS FirstName, 

              ssot__AnnualRevenueAmount__c  

FROM ssot__individual__dlm" AS individual 

JOIN ssot__Account__dlm AS account 

ON individual.ssot__PrimaryAccountId__c = account.ssot__Id__c  

WHERE ssot__AnnualRevenueAmount__c >500000000 

When checked, I get the following error:   

 Challenge not yet complete in Data 360 

In the "High Value Customers' workspace, we can't find a query that joins individuals to their sales accounts and filters for individuals with annual 

revenue values greater than 500000000.  Make sure to use 'individual' as the alias for ssot__Individual__dlm, 'account' as the alias for ssot__Account__dlm, matching ssot__PrimaryAccountId__c to ssot__Id__c. 

What am I missing? Any help would be appreciated.
