Now for one last question. Is it possible to add a "BACK" button to the left of the "ORDER" button to serve as a browser back button? It would make my site look better.

} else {
document.getElementById('b1').disabled='true';
}
}
</script>
<font size=-1 face="Verdana">

<span style='float:left;text-align:right;'>
<input type="checkbox" name="option" id="option" onclick="javascript
:enableButton();">
<label for='option'>I have read and agree to the<br />
</label>
</span>

<input type="button" name="b1" value="ORDER" id="b1" disabled='disabled' onclick="top.location.replace('http://www.holiday-scooters.com/HSR/Booking_Agent.html');" />
