Character Sheet not working by ONE player

I play Eclipse Phase and we already played 2 online rounds. Suddenly at the very start our third round the Character Sheet of one of my player didn't work anymore. Data is still there but the Dice Throw won't work, it doesn't use the stats and Data anymore. For example if the player throws initiative it only throws 1D6 instead of 1D6+Stat and for Skill and Attributes nothing happens. But one player which created a character the same time around, it works perfectly fine. So what can I do?

HI Willy! I'm not familiar with that sheet at all, so I can't be of any technical help. But you might garner more attention if the name of the sheet was in your subject line, so that it could be more easily seen by people who use it. Also, there are 3-4 Eclipse Phase sheets, none of them produced by Roll20. It might be helpful to look on your campaign settings page and find the author. Usually there is some sort of contact link if you wind up needing more technical expertise.
