Passing string variable to HTML TITLE tag fails within Netscape but works well within IE.

Passing string variable to HTML TITLE tag fails within Netscape but work well within IE. I have a single page consisting of inventory items to be sold. When an item is selected, it passes the product name to a DETAIL page as part of the TITLE tag for the DETAIL page. My problem is: Netscape does not like the SPACES between the text and refuses to display the DETAIL page. Initially, I thought there might be some way to parse the string and add the ascii code for SPACE, but I wasn't sure if I was on the right track. Does anyone have a proven solution to this problem? I thought the pseudo code might look something like this: <?php function parse_and_change(&grab_string){ $string_holder=$grab_string; while stepping through the characters in this $string_holder { if character = " " (or some other representation) replace it with something that doesn't scare netscape or title tag } return $string_holder; } ?> <?php if (isset($HTTP_GET_VARS["itemname"])) { $title = (parse_and_change($HTTP_GET_VARS["itemname"] )); }else{ $title="Generic Product Title"; } ?> <html> <title><?php echo $title ?> </title> </html>
