Leveling up manually with a charactermancer sheet?

Sorry for the totally noob question. I started a game with some friends and they used the charactermancer feature to create their sheets. Now they're about to level up but we have found that the options provided with the "charactermancer" are limited... so we thought it'd be best to do this process manually... however we can't figure out how to modify the character sheets.... is there a way to do this?  Thanks!

If you don't own the PHB &amp; other books on Roll20, the charmancer options are limited. You can just edit character sheets directly without using the Charmancer Levelup, but doing so will likely result in porblems if you later buy the PHB and try to level up it later. How to edit each section of the sheet may vary a bit, you can check the wiki page for more info no how the sheet works: <a href="https://wiki.roll20.net/D%26D_5E_by_Roll20" rel="nofollow">https://wiki.roll20.net/D%26D_5E_by_Roll20</a>
