So you had the php echo resolved? Other html files I have resolve the php so I am stumped....

Have you a simple form that uses php that you could send me? To help me with my sanity as it must either be something incredibly stupid I am doing or something I am missing.

Thanks
Chris

The only other thing I can think of is that you may need to try single quotes ' instead of " double quotes.
<input type="text" name="Old_Addr1" value= "<?php echo 'It works! again';?>" readonly>
If the php code doesn't echo inside the form input value does it echo outside of it or on a html page all by itself as I did in the test.html? If it doesn't echo you should get an error_log in the same directory as the echo is taking place.
