Ah, I didn't see the ".=" concatenators there...  You'll need to switch

    if (PageExists($prb)) $rpage = ReadPage($prb);
    if (PageExists($grb)) $rpage .= ReadPage($grb);
    if (PageExists($srb)) $rpage .= ReadPage($srb);
    if(@$rpage['text']=='') {...}

to something like

    if (PageExists($prb)) $rpage = ReadPage($prb);
    if (PageExists($grb)) @$rpage .= ReadPage($grb);
    if (PageExists($srb)) @$rpage .= ReadPage($srb);
    if(@$rpage['text']=='') {...}

When $prb doesn't exist, then PHP is complaining because
you're concatenating something onto $rpage which hasn't been
given a value yet.

Another way to all of the @-signs is to make sure $rpage
is initialized, as in:

    $rpage = array();
    if (PageExists($prb)) $rpage = ReadPage($prb);
    if (PageExists($grb)) $rpage .= ReadPage($grb);
    if (PageExists($srb)) $rpage .= ReadPage($srb);
    if($rpage['text']=='') {...}
