Hotspot script not working

[Anubhav Yadav <anubhav@icoer.in>]

Hello List, 

I used to make use of this script extensively when I was using ubuntu. 
It used to work perfectly out-of-the-box.

But on debian when I start the script, it runs without any error, but
the hotspot is never shown on my mobile.

When I restart the script, I get this error message:

	Restarting Wireless Hotspot...
	Stopping Wireless Hotspot...
	mon.wlan0: ERROR while getting interface flags: No such device
	Starting Wireless Hotspot...
	Wireless Hotspot active

The script is here http://paste.debian.net/33549/

And I downloaded the script here:

Any help will be appreciated.
