Survey123: constraint on percentage field?

Question

Apologies if this is very basic..My survey formular contains a "% mortality" filed. I would like to constrain users to entering values beween 0 and 100.

I have looked here, and here, but could not derive a working solution from either page.

Any ideas?

Many thanks!!

Hi Hélène, You would need to create a compound statement using both less than (<) and greater than (>), using the and operator to specify that both parts of the statement must be true. Using the period (.) to refer to the value of the question, the constraint would be: . > 0 and . < 100 If 0 and 100 are allowed as values, use >= and <= instead of > and <.
