Number Fields only accept positive numeric characters. Negative numbers, such as ‘-99’ will not pass the validation.
To add a number field to your form, click on the Add Field button at the top and click ‘Number’. You can click the field in preview and edit the field settings at the left side bar.
The Range setting limits the amount of data the visitor can enter. The range type ‘Digits’ represents the number of digits that the field will accept, such as “00” (Digits: 2) and “00000” (Digits: 5). The range type ‘Value’ means the value of the number entered by the visitor. Seven (7) will not be accepted by a field that the minimum range is set to eight (8).
