Is it possible to make exclusively digits mandatory?

[Erwin Holkin]

I'm adding custom visible fields to a request form. On one or two fields I'd like to set exclusively digits as mandatory. Is it possible to only allow the input of digits?

Hi @Erwin Holkin - You can make a numeric custom field or use the free Unique Regex Custom Field app to use a text field but require the contents to be numeric.
