Following the below guidelines I am trying to create two printer
buttons. When you click on the button it will print out a specified
frame.

The code I am using for the printer button is as follows:

on (release) {
printNum (19,"bframe");
}

19 is the frame number in that timeline. What do I need for that first
element (where the 19 is)?

I have two layers inside a timeline, event 1 and event 2.

Event 1: on frame 9 I have a printer button. When you press the button
I want it to print out what I have in frame 19. In the "Frame" text
box for frame 19 I have #p.

Event 2: on frame 14 I have a printer button. When you press the
button I want it to print out what I have in frame 24. In the "Frame"
text box for frame 24 I have #p.

This generates an error message when I run a test movie. The error
message is as follows: WARNING: Duplicate label, Symbol=Calendar Movie
Clip, Layer=Event 2, Frame=24, Label=#p

THE BELOW GUIDELINES:
Specifying printable frames

To specify which frame or frames you want to print when your viewers
choose Print from the Flash Player shortcut menu, follow these steps:

1. With the movie open, choose Window --> Panels --> Frame to open the
Frame panel.

The shortcut is Ctrl+F (Windows) or Command+F (Mac).

2. Select the frame in the Timeline that you want printed.

3. In the Frame panel, type #p in the Label text box.

For each additional frame that you want to specify for printing,
select the frame and label it #p.

Thank you,
Colin
