In the form designer, click + Add visible field, then choose integer as the field type.

integer: prompts the user to enter some whole number (no decimals). If you include "show_formatted" in the appearance column, a formatted version of the number will be displayed as the user enters it (e.g., as in "120,000" for "120000"); any formatting will follow the user's locale settings to be appropriate to the local context.

Integers are limited, by nature, to be nine digits or less. If you need more than nine digits, use a text field with the "numbers" appearance.

In the spreadsheet form definition:

type	name	label	appearance
integer	fieldname	question text
integer	fieldname	question text	show_formatted

Previewing fields and appearances

Click the hyperlinked field type above – or a hyperlinked appearance style, if any – to see a preview of the field or appearance in SurveyCTO Collect.

More options using field plug-ins

If you want to further customize an integer field, you can use a field plug-in, which gives you complete control over the field's appearance and functionality. For more information on using existing field plug-ins, see the using field plug-ins help topic. If you want to learn about developing your own field plug-in, see the developer documentation. You can also learn more about field plug-ins in our Guide to field plug-ins. For a list of all available field plug-ins, check out our Field plug-in catalog.
