​
Overview

Filla supports three numeric field types that map directly to their Airtable counterparts: All three share the same core settings.

​
Settings reference

Universal settings that also apply: Label, description, required, read-only, show/hide rules, conditional read-only, reject duplicates, custom validation rules.

​
Using min and max values

Min and max values enforce numeric range constraints. The form validates on blur and again on submission. Example uses:
  • A “Quantity” field with Minimum value of 1 and Maximum value of 100 prevents respondents from entering 0 or 500
  • A “Rating” field with Minimum value of 1 and Maximum value of 10 keeps scores in range
  • A “Discount percent” field with Maximum value of 100 prevents impossible discounts

​
Opinion scale display

When you switch Display style to Opinion Scale, the field still saves a number to Airtable, but respondents answer by clicking a value on a scale instead of typing. This is useful for:
  • satisfaction scores
  • recommendation likelihood
  • agreement scales
  • 1-to-5 or 1-to-10 evaluations
You can use Min label and Max label to anchor the ends of the scale, for example:
  • Strongly disagree → Strongly agree
  • Not likely → Very likely
  • Poor fit → Perfect fit

​
Currency and percent display

The currency symbol and percent sign are inherited from your Airtable field configuration. Filla reads them from the field’s settings in your base. You configure the symbol and format in Airtable, not in Filla.

​
Common questions

Yes. Airtable number and currency fields support decimals. The form accepts decimal input as long as the Airtable field is configured to allow them.
Yes. Opinion scale is only a display style. The saved value is still numeric, so you can use it in Airtable formulas, filters, automations, and reports.
Default values support @ variable references to other form fields, not Airtable formulas. You can reference a previous field’s value to pre-fill a calculation-style default.
The field only accepts numeric input. Non-numeric characters are rejected immediately. The respondent cannot type letters or symbols in a number field.
