Hello,

I've a problem with dialog-form.
I can't modify input fields but I can modify the select field.

I don't understand why.
Can you help me ?

My script
[code]
.....
$('#dialog-form').load('passagers.php').dialog({
autoOpen: true,
title: 'Nombre de passagers.',
width: 450,
resizable : true,
modal: true,
position: 'center',
buttons: {

'OK':function() {
alert("Hello");
}
}
}).height('auto');
.....
[/code]

passagers.php
[code]

Veuillez renseigner le nombre de passagers :
