Hi, since upgrading we are having an error with one of our existing surveys. This question is one with 9 boxes which you can drag or click to your preference. Here is the error, I have no idea what it means and would really appreciate some pointers. Thank you!

What version of LimeSurvey is used? There are some issues around signaling errors, which are none.
So you can ignore some of them. Bugfixes are on the way or already implemented.

You use numeric only question code : this is disable since 2.05 if i remind …
Put a alphabetic character before th 17, i think its fix the issue.

Yes, that was it! I renamed it 'Q17' instead of just '17' and the logic error is gone. Many thanks.
