Line of text in header multiplies into 2 paragraphs

To show a blog directory that I was the owner of my site I pasted their brief link line of text at the end of my header. I just checked & that text seems to have disappeared and been replaced by 2 fat paragraphs, which seems like a lot of blah blah for a simple link. Can anyone decipher this code?

<script type="text/javascript">
<!--
function bb2_addLoadEvent(func) {
	var oldonload = window.onload;
	if (typeof window.onload != 'function') {
		window.onload = func;
	} else {
		window.onload = function() {
			oldonload();
			func();
		}
	}
}

bb2_addLoadEvent(function() {
	for ( i=0; i < document.forms.length; i++ ) {
		if (document.forms[i].method == 'post') {
			var myElement = document.createElement('input');
			myElement.setAttribute('type', 'hidden');
			myElement.name = 'bb2_screener_';
			myElement.value = '1251678258 69.86.110.247';
			document.forms[i].appendChild(myElement);
		}
	}
});
// --></script>

Many thanks to anyone who can give me a clue here.
