php echo not working after elseif

I am trying to extract data from an XML file using simplexml. I am running a series of while and foreach loops to dig down to what I need.

However, I have found that after the elseif is finished I can no long display additional data to the screen (echo and print_r don't work). I have attached a code snippet for the elseif loop through the end of the end of the script. Please excuse the lousy code, I am a relatively new programmer.

elseif ($select_vars[1]==-1) {
    $sub1=0;
    $sub2=0;
    $temp_count = 1;
    $modnum=intval($select_vars[0]);
    $sub1m =  $xmls->module->{
        intval($select_vars[0])}

    ->count();
    while ($sub1 < $sub1m) {
        foreach($xmls->module->{
            $modnum}

        ->sublist1->{
            $sub1}

        as $hit2){
            $sub2m =  $xmls->module->{
                $modnum}

            ->sublist1->{
                $sub1}

            ->count();
            while ($sub2 < $sub2m) {
                foreach($xmls->module->{
                    $modnum}

                ->sublist1->{
                    $sub1}

                ->sublist2->{
                    $sub2}

                as $hit3){
                    $template_string .= $temp_count . " - " . (string)$hit3 . "<br/>";
                    $temp_count = $temp_count+1;
                    $template_list[] = (string)$hit3;
                }

                $sub2 = $sub2+1;
            }

            $sub1 = $sub1+1;
            $sub2 = 0;
        }

    }

    echo "sub1 = " . $sub1 . "<br/>";
}

echo "here <br/><br/>".$template_string;
print_r ($template_list);
$template_list = array_unique($template_list);
sort($template_list);
print_r ($template_list);

I know the loops extract the right information because I can echo anywhere in the various loops except after the esleif closing bracket.

EDIT:

The output SHOULD be 3 selects and when the top box is filled when the others are empty a series of line (up to 400+) in the format ### - ####-####-####-#### should appear.
