Validate Form Suite
This suite of Actions allows you to validate form elements on a page. It checks to see if a form element has been completed before submitting sending the data to the server.
Unlike the previous validation Actions, this suite can be applied to ordinary form items on a page, allowing it to work alongside other Actions (including DataDesigner).
There is also an Extras Action that allows you to customise the error messages.
The download includes instructions in PDF format.
