OK, there is something going wrong with the one-click install process... the script itself is fine, and it works if you "import" the script rather than "install" it from the one-click... and it also works just to go to the directory on github, get the raw code, and paste it in. All of that works just fine, but something is going wrong in the automatic process. For now, there is a newer version than the 1-click anyway... and though I just submitted it to the one-click to be merged in, it will take probably a week before it comes through the system that way. Hopefully, the new version will reset whatever is going wrong. But if you go to my personal repo , you can copy it into your game and it should work (click on the js file, then click on the "Raw" button; select everything and copy it; delete the existing Hero Roller installation, and paste the code into a new Script tab that you call "Hero Roller"). That should get you by for now. Next week after Tuesday, when they process the Pull requests to merge the new code in, the new Hero Roller should be available from there and you should be able to go back to using the 1-click version. *Should* be. Here is the original thread where I introduced Hero Roller: Community Forums: [Script] HeroRoller (calling Hero System Beta Testers) | Roll20: Online virtual tabletop And the post where I released version 1.2.1: <a href="https://app.roll20.net/forum/permalink/9956423/" rel="nofollow">https://app.roll20.net/forum/permalink/9956423/</a> Let me know if you have any more trouble, or need any help with the syntax. And happy gaming!
