Validation formulas will run input a user enters against a formula. If the input does not meet validation requirements, an error will appear on the form screen in the Axsy Mobile App. Depending on whether the element is a required field or not, the type of error will vary. 

Run the Smart Form on the Axsy Mobile App 

1. If you have an Element that is not required but has a validation formula, an input error will only occur if the field is non-empty and does not meet the formula requirement. 

2. If you have an element that is required (a mandatory field) and you leave it blank, an error window will prompt you to fill in the mandatory field. 

3. If you have an Element that is required and has a validation formula, you cannot leave the field blank and will have to meet the validation formula requirement to continue with the form.
