Input Image Post on Click

programming
1

The bottom example works in Firefox but not in IE.

Example:

<form method="POST" action="?action=testing">
button1: <input type="image" name="btn" id="btn" value="VALUE 1" /><br />
button2: <input type="image" name="btn" id="btn" value="VALUE 2" /><br />
button3: <input type="image" name="btn" id="btn" value="VALUE 3" /><br />
button4: <input type="image" name="btn" id="btn" value="VALUE 4" /><br />
button5: <input type="image" name="btn" id="btn" value="VALUE 5" />
</form>
<?php
if($_GET['action'] == 'testing'){
 print($_POST['btn']);
}
?>

What I want to Happen:
Button 3 is pushed so that ($_POST[‘btn’] == “VALUE 3”) = true
Question:
So this possible or not?

Conclusion:
Not supported by IE. Given up and recoding system.
