Trying to add some html/css to my $message

so i have my $message working fine , it has some echo variables , really simple stuff .
but id really like to stylize it a bit , add a jpg banner on the top , stuff like that .

ive been here : , and tried to make my message all html , but then for some reason it doesnt pick up any of my php strings or variables .

sorry im still kinda php illiterate , but does anyone have any suggestions ?
