I want to ensure that users can only enter 16 digits

[veentzy]

Hi, I have a different case: I want to ensure that users can only enter 16 digits. Therefore, I’m using this regex pattern: regex(., ‘^\d{16}$’). It works as expected in a browser, but when I try it in a mobile app, it gets stuck, allowing a maximum of only 7 digits. I cannot enter more than 7 digits. Why is this happening?

Because you use an integer type. You would need to use a text type with appearance number.

Hint: Often the Help Center articles and/or the search function of this forum can provide help and examples, e.g.

• Limits on Number and Text Responses — KoboToolbox documentation
• Number, Decimal and Range Question Types — KoboToolbox documentation
• Search results for 'limit number of digits' - KoboToolbox Community Forum.
