You can combine upload and download into one script by using an action parameter on the buttons. For example

<!DOCTYPE html>
<html>
<head>
<title>MAINTENANCE PAGE</title>
</head>
<body>
<form action="Maintenance_Framework.cgi" method = "post" enctype="mult
+ipart/form-data">
<h3>MAINTENANCE PAGE</h3>
<p>
Circle:
<select name="Circle" >
    <option value="Gabon">Gabon</option>
    <option value="Tanzania">Tanzania</option>
</select>
Technology : 
<select name="Techno" >
    <option value="Core">Core</option>
    <option value="RAN">RAN</option>
  </select>
<input type="submit" name="action" value="Download"/></p>
File to Upload: <input type="file" name="filecsv"/>
<input type="submit" name="action" value="Upload"/>

</form>
</body>
</html>
