I have index.html page with tables rows and cells.
Within table I have:
<table width="100%">
<tr>

<td class="form-font" width="40%" align="left">
<iframe src="create.html" width="100%" height="200" frameborder="no" scrolling="no">
</iframe>

</td>
create.html is:
<html>
<head>
<title>Results Operation</title>
</head>
<body>
<form action="/cgi-bin/script.cgi" method="POST">
<fieldset>
<legend>Form fields</legend>
...
...
...
</fieldset>
</form><br/>
</body>
</html>
but in index.html iframe appears as
Not Found

The requested URL /cgi-bin/create.html was not found on this server.
Apache/2.2.12 (Ubuntu) Server at localhost Port 80
create.html and index.html are both in /var/www directory.
Why create.html appears in /cgi-bin directory?
