Greetings,

I can't seem to figure out why I am getting the following error.  I have the "Name" field in my test class and have confirmed it is not NULL using system.assertvalue.  What am I doing wrong?  Thank you in advance for your help!!!

Error Message:::::::: System.DmlException: Insert failed. First exception on row 0; first error: REQUIRED_FIELD_MISSING, Required fields are missing: [Name]: [Name]

Stack Trace::::::   Class.multirecords.save: line 20, column 1
                              Class.TestMultiRecords.TestMultiRecords: line 36, column 1
