Sheila,
The problem is that this (the 'value=""' ' entry) appears on the form:
<?=$_POST['last_name'];?>
and similar entries in the other input windows. These do not clear and
have to be deleted when the requested detail is being inserted.
The script does what you describe and returns the form with a message
specifying where the fresh entry needs to be made. But can this be
achieved only with the little piece of script turning up on the form when
first called? And having to be deleted? In the book the fields are shown
blank, but I cannot see anything that I am not copying as instructed.
And, although the form code has this
<input name="req" type="hidden" id="req" value="process" >
and the script has this
switch ($_REQUEST['req']) {
I get an error message that 'req' is not defined. I mention it because it
seems possible the two problems are connected.
