One of the questions I get asked again and again is how to validate a field value in an Acro Form with a custom validation script.Adobe provided a lot of infrastructure to do that with just a simple script.Currently, if you leave the captcha empty and submit the form, the field will be masked as invalid.Validating data in Microsoft Access allows you to check data whilst it is being entered by the database user and will enable you to not save the data if it breaks any validation rules or routines.Here you can see screen captures from Firefox and Chrome: Text alert messages are generated entirely by the browser and will even translate automatically into different languages - something that would be almost impossible using just Java Script.The advantage for the user is that it's obvious whick element is causing the problem and there's no alert window that needs to be clicked away.
