Hi Paige,
You added the links perfectly. I think that what Tom is suggesting is that you list all the information about the source in the citation. When you use familysearch records for sources, they give you a citation that you can use, which makes it very easy. I clicked the one for the death certificate and here's what is on the familysearch page under the record::
CITING THIS RECORD
"United States Social Security Death Index," database, FamilySearch(https://familysearch.org/ark:/61903/1:1:V3NV-1JM : accessed 7 September 2015), Ora Millard, Jun 1975; citing U.S. Social Security Administration, Death Master File, database (Alexandria, Virginia: National Technical Information Service, ongoing).
Instead of your line citing that record, you could have put an asterisk as the first character on the line (that makes a bullet on the view page) followed by a paste of that citation as follows:
* "United States Social Security Death Index," database, FamilySearch(https://familysearch.org/ark:/61903/1:1:V3NV-1JM : accessed 7 September 2015), Ora Millard, Jun 1975; citing U.S. Social Security Administration, Death Master File, database (Alexandria, Virginia: National Technical Information Service, ongoing).
That gives all the information about the source and includes the link to the record. The statement you have in the sources section could then be put in the biography section, with the source citation supporting that statement.
