Apache PHP Module not working (everything else is) - HELP!!!

Hi, If anyone can help me with this, I would really appreciate it! ok, Got Apache 1.3, installed on an NT4 box, with MySQL and PHP4 I can query the MySQL db with PHP, but ONLY in a standalone DOS box, the rows are returned, as requested, no problem... I had been starting Apache in a DOS box, before installing it as a service. When starting with DOS box, the banner declares that PHP has been loaded, so know the PHP module has been loaded, but... *** Cannot use PHP, via code embedded in html doc, i.e. apache doesn't seem to be redirecting the PHP commands to PHP, the page is just blank, with no error message! *** I'm sure I've followed all the intructions in "install.txt" that came with PHP, but it's drivin me NUTS! I'm pretty sure that it's a conf thing in httpd.conf (apache's def conf file) can ANYONE help??? Cheers, bm
