How do I customize the error messages for invalid inputs?

To customize error messages for invalid inputs, navigate to the field settings in your form builder, where you can edit the default error messages. You can personalize these messages to provide clearer instructions or use a tone that aligns with your brand's voice. For example, instead of a generic "Invalid input" message, you can specify what the user needs to correct. Customizing error messages helps users understand and resolve issues quickly, reducing frustration and ensuring a smoother form-filling experience.
