Good morning, hoping for assistance. Making one of the third columns a number entry will stop customers putting a question mark, or you tell me, when we’re looking for a required amount is £ from them. This is for an insurance quote form.

This is not a feature of Gravity Forms but you can create your own custom validation routine for the data entered in your List field using the following filter: [gform\_field\_validation - Gravity Forms Documentation](https://docs.gravityforms.com/gform_field_validation/)
