how can I put a constraint on a text question which does not allow spaces to be entered?
is it possible to put a constraint on an integer question type which allows you to only put in multiples of 5 for example? If so would you have the formula?
Much appreciated in advance,
For 1: constraint:
regex(., ‘^[^ ]+$’)
- ^ asserts position at start of a line
- Match a single character not present in the list below [^ ]+
+ Quantifier — Matches between one and unlimited times, as many times as possible, giving back as needed (greedy)
" " matches the space character literally (case sensitive)
- $ asserts position at the end of a line
For 2: constraint:
. mod 5 = 0
See Math Operators about the mod operator; it returns the remainder after integer division.
