Why do i get a syntax error when i try to run this code?

[scott dieken]

x=3
title = "PHP Programing"
author = "LERDORF"
publisher = "oreily"
major = "cent"
outfile = open("book.html","w")
outfile.write ('<html>\n')
outfile.write ('     <body>\n')
while ( x > 1 ):
    outfile.write('     <p class= "title">' + title +'</p>\n')
    outfile.write('     <p class= "author">' + author +'</p>\n')
    outfile.write('     <p class= "publisher">' + publisher '</p>\n')
    x = x - 1
outfile.write ('     </body>\n')
outfile.write ('     </body>\n')
outfile.close()
