Ammad is right, with the Message built-in the only way you can push the content of the Message into a popup is to call Message() twice. Thankfully, there are three different types of Alerts you can create (Note, Caution and Stop). Most Forms applications I've worked on had a wrapper class they used to display messages in one of the three different Alert types or in the status bar through a single call. The wrapper class was an overloaded library procedure that displayed the desired message with a single call rather than multiple calls required for an alert. For example, create a library package called MSG with a single exposed procedure called DISPLAY (or what ever you want to call it) and overload it so you can pass a message text, alert type, button names, etc. Here is an example of the procedure signature:
CREATE OR REPLACE PACKAGE MSG IS
   /* Define the types of Alert Button Titles that are allowed */  
   /* You could use a VARCHAR2 parameter that allows the user */
   /* to specify the Button Title, but I prefer to define the titles */
   BTN_OK        CONSTANT NUMBER:= 1;
   BTN_CANCEL    CONSTANT NUMBER:= 2;
   BTN_SAVE      CONSTANT NUMBER:= 3;
   BTN_YES       CONSTANT NUMBER:= 4;
   BTN_NO        CONSTANT NUMBER:= 5;
   --ETC......
   /* Define the Alert Types */
   TYPE_NOTE    CONSTANT NUMBER := 1;
   TYPE_CAUTION CONSTANT NUMBER := 2;
   TYPE_STOP    CONSTANT NUMBER := 3;
   /* display text in Status Bar */
   PROCEDURE DISPLAY (p_msg_txt VARCHAR2); 
   /* display text in an Alert with just one button */
   PROCEDURE DISPLAY (p_msg_txt VARCHAR2, p_msg_type NUMBER, p_btn_1 NUMBER);
   /* display text in an Alert with two buttons and return button pressed) */
   PROCEDURE DISPLAY (p_msg_txt VARCHAR2, p_msg_type NUMBER, p_btn_1 NUMBER, p_btn_2 NUMBER, p_btn_pressed OUT NUMBER);
   /* display text in an Alert wit three buttons and return button pressed */
   PROCEDURE DISPLAY (p_msg_txt VARCHAR2, p_msg_type NUMBER, p_btn_1 NUMBER, p_btn_2 NUMBER, p_btn_3 NUMBER, p_btn_pressed OUT NUMBER);
END MSG;This of course, is just the Package Specification, but it demonstrates the concept. This overloaded procedure in turn calls a private package procedure that does all the work of setting the alert properties, displaying the message text, recording which button was pressed and return the button pressed to the p_btn_pressed OUT parameter. Using this method - or a similar method - it allows you to display a message to your users with minimal coding. If you are working with a multi-language application, you could change the p_msg_txt parameter to a NUMBER that would refer to a message stored in a table.
Hope this helps,
