Hi,
I want to have a select field like that with the following choices:
>> please select
Option 1
Option 2
Option 3
How can I check that the user has selected one of the options and not the first entry '>> please select'?
Thanks
Martin

that is only posible when the first option has no value.

Thanks. How do I get it to have no value?
I use the following code:
$arraysplit = split("\r\n", $form_setup_values);
$number = count($arraysplit);
$l = 0;
while ($l < $number) {
$value = $arraysplit[$l];
$array[$value] = $value;
$l++;
}
if ($form_setup_required == 'Y') {
$check = FH_NOT_EMPTY;
$form_setup_caption = "<strong>" . $form_setup_caption . "</strong>";
} else {
$check = "";
}
$value = $form_setup_default;
$form->SelectField("$form_setup_caption", "$form_setup_db", $array, $check);
if ($form_setup_helptext)
$form->setHelpText("$form_setup_db", $form_setup_helptext);
if ($value)
$form->setValue("$form_setup_db", "$value");
$form->setErrorMessage("$form_setup_db", "$form_setup_error");

$array['']= 'option 1';
$array['2'] = 'option 2'
and than use the keys as a value (5th argument of a selectfield)
that is exactly why most people use a please select, that is the option without a value.
