I would suggest updating both to the most recent version if you are trying to solve a problem. Roll20 made some changes in their code that made massive problems for older versions of the sheet and script. Kryx has been doing damage control for some time, and the latest version of each not only fix most if not all of those problems, they are the only version for which he offers support. If you still have the problem after upgrading, use the report link at the bottom of any character sheet to open an issue on his tracker, including version number and reproduction steps. You'll get a much better answer than any of us trying to guess at the issue.
