Not sure what you're really after here but to join 2 vars together you need to do this (and note the end php correction I made)
<frame src="fac.php?id=<?php echo $_GET['id'].$_GET['spl']; ?>"></frame>
Instead of this
<frame src="fac.php?id=<?php echo $_GET['id']& echo$_GET['spl']/></frame>
In other words, say you have 2 vars.
$var1 = 'the';
$var2 = 'words';
Echo $var1.$var2; // prints as 'the words'
Hope that makes sense.
