I have a multiple numeric input question, it has 5 subquestions.
Minimum value is 0
Maximum value is 52
Sum must equal 52
Question is NOT mandatory.


I enter in the following values: 52,0,0,0,0 and I get the following error:

One or more questions have not been answered in a valid manner. You cannot proceed until these answers are valid.


I've also tried 48,1,1,1,1 and numerous other permutations, I always get that error.

Which version/build of LimeSurvey is used?

The input settings are these:
Minimum value:
Equals sum value:
Integer only:
Maximum characters:
Value range allows missing:

Minimum sum value:

Which fields are set?

Try to reproduce this question in the demo installation of LimeSurvey.

I'm not sure what went wrong, but I just simply deleted both questions and recreated them with the same settings and they work now.
