Problem posting form to Self when using dropdowns.

[ebanbury]

Hi
Can anyone tell me why my form will not post to itself when using these dropdowns.
It will post successfully to another page though. I have tried both just putting in the file name which is rent.php and using the "<?php echo $_SERVER; ?>"

At the moment I am just trying to echo the results of what is selected in the dropdowns to the same page but even that is not working....any help would be fantastic.

many thanks
