Validation text refers to messages or prompts that provide feedback to users regarding the correctness or completeness of the data they have entered in a form or application. It helps ensure that the information meets specific criteria, such as format or required fields, before submission. This text can guide users in correcting errors or confirming successful entries, enhancing the overall user experience.
The Validation Text in MS Access is the text that is shown when the conditions set by a Validation Rule are not met. In Access you can specify a Validation Text for each field in a table's Design View in the Field Properties panel.

A Validation Text Property
Generally client side validation uses functions or a validation object and methods to check that a user has entered valid data, and that all required data is entered. Validation for text fields is often done by attaching a function call to the "blur" event of the text element. Validating that all required data is present is normally done by attaching an event to the "submit" event on the form. In all cases, you have to be aware that client side validation is only useful for user experience. It cannot be relied on, and so even with it, server side validation has to be done on the submitted data. This is true even in cases where AJAX is employed, as all client side code is suspect.
There are basically two levels of data validation in Access. The first level can be specified by the Access developer in the form of validation rules or input masks. The second level is the actual constraints that Access enforces for input into a field. Access will not allow you to add text into a Number field for example.
To have your own message displayed when a user tries to enter data that does not meet your validation requirements in a field in Microsoft Access open the table in design view. Immediately below Validation Rule you will see 'Validation Text'. Click next to that and type in the message that you want to be displayed. If you had made the Validation Rule >=25 you could type the following as validation text and it would appear in the message box that would appear if a figure lower than 25 was entered. The rate per hour cannot be less than €25. Please enter a figure greater than 25.
To create a validation rule in Microsoft Access, open your table in Design View and select the field you want to validate. In the Field Properties pane at the bottom, locate the "Validation Rule" property and enter your desired expression (e.g., >=0 for non-negative numbers). You can also set the "Validation Text" property to provide a custom error message when the rule is violated. Finally, save your changes to enforce the validation rule when data is entered or modified in that field.
