[Help] Need some help

Hi all, I am unfamiliar with CSS, HTML or Java and am trying to figure out how to modify the character sheet so that some of my cleric abilities work. I play a light domain cleric and am looking specifically for help with Channel Divinity: Radiance of the Dawn.  I'd like to be able to press a button and have the 2d10+level damage rolled by a macro. Unfortunately when I look at macros people have written, my brain stops working.

You can use this in your class actions section of your character sheet.  Additional [[2d10+@{cleric_level}]] radiant damage! Then you can just click the "use" button on that class action to output it to chat.
