and... I agree, I just start using globals to start then after I have it working I change 'em (bad habit).

    (defop test req
	   (let parm (arg req "parm")
	   (prn parm)
	   (br)	
           (if (is parm nil)
	       (do-it "test" url parm))   
               (do-it (string "test?parm=" parm) parm)    
    ))

    (def do-it (url parm)  
        (form url (gentag input type 'hidden name 'parm   value parm)
        (textarea "stuff" 10 50)
        (br)(submit))
    )
