    How come I can't get the code to continue after this?
    if (!$name){
    echo"No search term given.";
    echo $link;
    exit;
    }
    This is only it the field is blank, if not blank should continue.
    BUT it don't, but it is doing my head in.:)

    Have you defined $name above this?
    I presume you are posting from a form or something so it could be that.

    Didn't expect a thank you like that - thanks!

    Just to let you know, this may have worked in older versions of PHP but this was a security issue so they disabled global variables. So you will have to access POST, GET data via the $_POST or $_GET array. $_REQUEST catches both.

    Writing in Dreamweaver will make no difference what so ever. Its just an editor when coming to code - there are more advanced editors out there that may be better when writing PHP code. I've used PHP Designer a lot but it costs. Do a search here or google and you'll find free versions of software that may help or give you hints to syntax.
