I am getting an error that shows up in my webserver
error logs which says:

"Use of uninitialized value at....."

Problem is it is coming from the HASH which stores the
CGI variables passed to the script. How can I get rid
of it?

this is the problem code, but note it works fine.
%USERDATA is the problem child.

sub main {

	# Get the output from the browser
	%USERDATA = &getData;

	SWITCH: {	
		if ($USERDATA{"mode"} eq "login")   { &login;    
last SWITCH; }
		if ($USERDATA{"mode"} eq "logout")  { &logout;   
last SWITCH; }
		if ($USERDATA{"mode"} eq "help")    { &help;     
last SWITCH; }
		if ($USERDATA{"mode"} eq "go")      { &go;       
last SWITCH; }
	
		&start;
	}
};
