[Balallar]

I'm sitting on a from trying the Coldfuion XMLFormat() function.However if I do this:\[code\]<form name="sample" action="#cgi.script_name#" method="post"> <input name="test" value="http://stackoverflow.com/questions/10364422/#XMLFormat( form.test )#" type="text" tabindex="1" /></form>\[/code\]I'm just getting CF-erors, that element test is undefined. What am I doing wrong?Thanks for input!
