Mixing HTML with PHP

Anon

For some reason the include goes to the top of the page, can someone tell em why?:

<HEAD>
<TITLE>Danny's Simple Guestbook</TITLE>
</HEAD>

<STYLE type="text/css">
BODY
{scrollbar-face-color: #0098EA; scrollbar-shadow-color: #0098EA;
scrollbar-highlight-color: #; scrollbar-3dlight-color: #C0C0C0;
scrollbar-darkshadow-color: #C0C0C0; scrollbar-track-color: #000000;
scrollbar-arrow-color: #3354E6}
</STYLE>

<BODY BGCOLOR="#6D96E0">
<TABLE BORDER=0 bgcolor="#C0C0C0" cellpadding=1 cellspacing=0>
<TD>
hihihihihi<BR>
<?
include("messages.txt");
?>
</TD>
</TABLE>

i) <head> and body should be inside .
ii) <style> should be inside <head>.
iii) <td> should be inside <tr>.

finished article should look like..

<HEAD>
<TITLE>Danny's Simple Guestbook</TITLE>
<STYLE type="text/css">
BODY
{scrollbar-face-color: #0098EA; scrollbar-shadow-color: #0098EA;
scrollbar-highlight-color: #; scrollbar-3dlight-color: #C0C0C0;
scrollbar-darkshadow-color: #C0C0C0; scrollbar-track-color: #000000;
scrollbar-arrow-color: #3354E6}
</STYLE>
</HEAD>

<BODY BGCOLOR="#6D96E0">
<TABLE BORDER=0 bgcolor="#C0C0C0" cellpadding=1 cellspacing=0>
<TR>
<TD>
hihihihihi<BR>
<?
include("messages.txt");
?>
</TD>
</TR>
</TABLE>
