Never mind. I figured out I was copying the wrong piece of code.
Just a pointer to anyone that is trying to add their own SVG following this link, it took me awhile to figure out what the author really did. She skips an important step that I didn't know I could do. Once you've created the SVG file and have it open in google chrome, you have to then right click on the image and click "Inspect". This will then bring up the box where all of the coding is that you can copy into your dashboard.
You can find the Custom screen when you go to the Indicator tab in indicator options and select either 'Left/Right' for the icon option. A couple of screenshots below for reference.
