[Help] changing Bloodied and Dead Status Markers

I'm new to all of this so bear with me if i am missing something but, I want to simple change the popular Bloodied and Dead Status Markers script to show the Half heart status instead of the the red marker, but i cant seem to get it to work.  I thought it would be as simple as replaceing the text of status_redmarker with status_half-heart, but it doesnt seem to work, anyone know what im doing wrong or if this just plain doesn't work?

The script in question uses the single-parameter version of obj.set , so status_redmarker is an object key. Hyphens are not legal characters in a JavaScript identifier. You can still use a hyphenated word as an object key, however, if you make it a string by wrapping it in single or double quotes. So, instead of: status_half-heart: true use: 'status_half-heart': true (and the same for the false line, of course.)

That did the trick, thank you very much!
