I am trying to DEBUG my GLOBAL PROCEDURE, so I tried to place a message in the code to pop up with a variable, so I can see if the variable is what it should be. THe code is this:

MESSAGE (carid||'-'||pon||'-'||ddate||'-'||descrip||'-'||cdate);

Oracle FORMS tells me I need to declare the varible 'MESSAGE'. How can I just create a pop up message to show the variable results.
Thanks!
