can anyone please help me to build a form with validation. I am using the form in a html page and it is processed in another php page. The form has only radio buttons for five options.for example cash.if the required cash is less than the user's cash in the datbase, the form should have a red highlight letters telling that the "cash is not enough" in the same page with form.
Regards!

$query="SELECT * FROM guns ";
$con=new Connection();
$con->setQuery($query);
$con->setDatabase('DB_NAME');
$sth=$con->runQuery();
?>
<form name="gunstransaction" action="process.php" method="POST">
<?php
$count=1;
