I have tried to add Client Side form validation (Java Script) to <BR>register.html page (Chapter 17.2 example), and also connected to the page RegisterUser(version 1).asp.<BR>After execution this Error message came out instead of Java Script warning:<BR><BR>"Microsoft OLE DB Provider for ODBC Drivers (0x80004005)<BR>[Microsoft][ODBC Microsoft Access Driver] Field &#039;tblUsers.LastName&#039; cannot be a zero-length string."<BR><BR>How can I insert JavaScript properly into a Form which will link to an .asp page?<BR>Is my Java Script code was possibly wrong, or there are some other restrictions with forms, which I don&#039;t know?<BR>
