Trying to establish exact number of characters for field.

[ALT46795]

Hello - I am creating a form in Adobe Pro and I would like to set a specific field to be nine characters (digits specifically), no more, no less. So when the person fills it out, an error will appear if they enter six digits and try to move on. Does anyone know how to do this? TIA!

Go to the field's Properties and under the Format tab select Special - Arbitrary Mask, and enter the following pattern:

999999999

Thank you! That worked, so easy! 🙂
