-The fourth column is a field which takes in a set of entries, where the options for entry are A, B or C. A set can have all these option within it however it does not accept duplicates. So an entry such as `SET(A,A,C)` would fail, but the entry `SET(A,B,C)` would be valid.

-Finally the sixth column is a record array field, a record array object can be entered with it with the corresponding fields testString and testNumber. A record array can also have multiple entries of the field within it, as long as the new entry is separated by a **";"**. Valid entries would be `RECORD_ARRAY(testString: A, testNumber: 1;)` or <br>
+Finally, the sixth column is a record array field. This record array object can have the fields testString and testNumber entered within it. These internal field values are entered by including the fieldname and its corresponding value separated by a **":"**. In addition, a record array can also have multiple entries for each internal field within it as long as the new entry is separated by a **";"**. With that in mind, valid entries for this column would be `RECORD_ARRAY(testString: A, testNumber: 1;)` or <br>
 `RECORD_ARRAY(testString: A, testNumber: 1; testString: 1, testNumber: 2;)`, etc.
