Incomplete data when registering number 0 'zero' at the beginning

Hi @datex
Welcome to the community forum. Have you tried using the text question and applying a regex formula? You can see previous discussions below

Number constraints

FYI all, the behavior between ODK Collect (aka javaRosa) and Enketo differs significantly regarding the necessity of start/end string delimiters; see https://github.com/getodk/javarosa/issues/531 for the gory details… So depending on which client you happen to use, a regex without ‘^’ and ‘$’ may or may not behave as intended. Strictly speaking, almost universally regex’s perform a partial match (ie any substring), so I always explicitly put them in when I actually want to check the entire str…
