Hi there, 

I am trying to save this trigger after I added a condition for the Account__c filed (line 13). Unfortunately, I am getting the following 2 errors: 

#1. Error: Compile Error: Duplicate variable: obj at line 13 column 31
#2 Error: Compile Error: Duplicate variable: obj at line 20 column 39
