Center message text

Hi,
I'm trying to display a message on the ADD page by using the "before add page is processed" event.

I want the message beeing centered, colored etc. This is my code:
Response.write "<font color=#FF0000 size=2><align center> IMPORTANT: Please use CAPITALS only </font>"
Result: Text is colored and in correct size but not centered.

What do I have to change?
Regards,

Philip
