Can we have an option to force values depending on other responses?

[Remi-Gau]

e.g. "min N trials should be forced to be lower than avg N and max N trials" or "N subjects included needs to be smaller or equal to number subjects selected"

another example: epoch beginning should be a smaller number than its end, the same goes for the measurement time windows

another example: Baseline period: end should be numerically bigger (more positive) than beginning

Dejan says: For start: to add a new column for simple numerical limits within one question (this is posted as a separate issue). Later we can think about validity checks BETWEEN items, but that is more complicated.
