If it really is his game, then he needs to set this up. I am not sure whether this custom Sheet is a Pro Only Feature or not. If it is, open the game for your friend and prep everything as mentioned here. Then have your friend join the game and make him GM. Then you only need to join as player and everything should be working out for you...

I have the pro subscription and wanted to set up a custom sheet for a game I'm in, however I'm not the creator. Thing is : my friend, who is creator, don't have the pro subscription and therefore can't set up a custom sheet. Is there a way for us to do it without him having to subscribe ? Btw, sorry if the question has been answered multiple times, kinda new to roll20 If your friend sends you the .html and .css file then you can upload them as a custom character sheet. You need to do the following: You create a new game and select to use a custom character sheet. Now click Settings -> Game Settings Scroll down to the big input field under the tab saying HTML . Insert your friends HTML code here. Click Save Changes Now scroll down again and select the tab saying CSS . Insert your friends CSS code here. Click Save Changes Your game is now set up with your friends code. As GiGs says. You now need to join the game as a player if you are the player. If you are the DM then you can just click Start Game. Hope this helps!
