like

echo "<div>$stylelogo <a href=\"acstyle/\">Style Yourself</a><br /></div>";

[adex3g]

Error Line 49, Column 62: document type does not allow element "br" here; missing one of "h1", "h2", "h3", "h4", "h5", "h6", "p", "div", "pre", "address", "fieldset" start-tag

echo "$stylelogo <a href=\"acstyle/\">Style Yourself</a><br />";

Try to change your doctype and head codes. I'll share you mine

<!DOCTYPE html PUBLIC "-//WAPFORUM//DTD XHTML Mobile 1.0//EN"
"http://www.wapforum.org/DTD/xhtml-mobile10.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<link rel="shortcut icon" href="favicon.ico" type="image/x-icon" />
<link rel="stylesheet" type="text/css" href="css/style.css"/>

Go to validator.w3.org then check this waprock.net/a/ it's validated

P.S

that page is just for demo using that doctype.

[adex3g]

I validate my adexchat.com, from validator.w3.org and it was full of error report, and i dont know my error. Pls tell me my errors
