popup based on the result of comparison
<p>The situation is that the user enters a value in the textbox.Now whenever user enters the value, the value is to be compared to a value(field) which has been retrieved form the database.If the value the user has entered is higher than that of the database then they should be displayed with a popup.How do i do that?The language which i am using is PHP.The popup should be automatic</p>

<p>Thanks in advance</p>
