So I have the following html script, and perl cgi script for a basic calculator for Apache. What I was wondering was if it is possible to add a button to the output from the cgi script, that links back to the original html file? Basically a button to start over again after the script gives you the answer. Any tips?

HTML 

<html>
<head>
<title>Simple Calculator</title>
</head>
<body>
<h1> Simple Calculator </h1>

<form action=/cgi-bin/calc.pl method=post>

<center>

First Number: <input type=text name=na maxlength=4 size=4><p>
Second Number (or Exponent Number): <input type=text name=nb maxlength
+=4 size=4><p>

Preferred mathematical operation:<br>
<input type="radio" name=oper value="mul">Multiply<br>
<input type="radio" name=oper value="div">Divide<br>
<input type="radio" name=oper value="add">Addition<br>
<input type="radio" name=oper value="sub">Subtraction<br>
<input type="radio" name=oper value="expo">Exponent<br>
<p>
<input type="submit" value="Submit form">
<input type="reset" value-"Clear all fields">
</form>

</body>
</html>

Perl CGI: 

#!/usr/bin/perl -w

use CGI ':standard';

$na = param('na');
$nb = param('nb');
$oper = param('oper');


if ($oper eq "mul") 
    { $answ = $na * $nb; 
    }
    
     elsif($oper eq "div")
    { $answ = $na / $nb; 
    } 
    elsif($oper eq "add")
    { $answ = $na + $nb; 
    }
    
     elsif($oper eq "sub")
    { $answ = $na - $nb; 
    $nd = "-";
    }
     else 
    {$answ = $na ** $nb;
    }
                      
    print   "Content-type:text/html\r\n\r\n";
    print    "<html>";
    print    "<head>";
    print    "<title> Answer Page</title>";
    print    "</head>";
    print     "<body>";
    print     "<H2> The answer to your calculation is: $answ </H2>";  
+   
    print    "</body>";
    print    "</html>";
