Just for additional information,
* If you don't apply the second parameter to the add function, it will just default to using the first one as well, so no need to specify twice.
* It's probably best to load these into a global script (usually DataCommon in many of the existing rulesets) as a table you can pull these values from, instead of hard-coding within the control. Easier for long-term maintenance.
