Dropdown Select using DB data

I just don’t get it. The “test data source” returns correct results. No errors in console or debug but will not show up using this:

[select vehicleyears][cf7-recordset id=”cf7-recordset-284″ type=”database” query=”SELECT DISTINCT year FROM car_db”][cf7-link-field recordset=”cf7-recordset-284″ field=”vehicleyears” value=””]

Any help would be appreciated, testing this on local currently and have the CF7 Smart Grid extension in use.
