    Default Form Field validation

    Hi all,<BR><BR>just a quick question.<BR><BR>I want to be able to check the contents of a form field against a column in a table, can it be done and if so how.<BR><BR>Example : <BR>User inputs surname into form field.<BR>on exit or onchange - the application checks if surname exists in table.<BR><BR>If not surname is accepted.<BR>OR<BR>If surname already exists, either a message box appears, which when clicked shows results of table, or user is taken to another page with results.<BR><BR>Can this be done.<BR><BR>hope this makes sense.<BR><BR>Cheers all.<BR>
