 * I’m new to Javascript but not to programming.
 * When i use this snippet it works ok and field displays 180:
    (function(){ var
   volw1 = 180; var volwx = 60; var kind = 50; var ret = volw1; return ret; })();
 * But when added one line to display a date field the field doesn’t get calculated
   and is empty:
    (function(){ var volw1 = 180; var volwx = 60; var kind = 50; var
   ret = volw1; windows.alert(fieldname30); return ret; })();
 * Why?

 * Hi,
 * Because in javascript the object is called ‘window’, in singular, the object ‘
   windows’ does not exists, so, your code provokes an error that is stopping the
   javascript execution.
 * Best regards.
