prev/next button problems

Hi, I have a problem, i’m using your plug in in my web site, but i have a big problem with the prev/next buttons, I used the slide rigth and it works, when I put the prev/next buttons i do in this way:
in the header.php in a <script> i put

jQuery('.total-slider').cycle({
	speed:          1000,
	timeout:        11000,
	prev:       jQuery('#total-slider-previous'),
	next:       jQuery('#total-slider-next')
});

and also

jQuery('.ts-default').cycle({
	speed:          1000,
	timeout:        11000,
	prev:       jQuery('#total-slider-previous'),
	next:       jQuery('#total-slider-next')
});

the last one class is the slide class, after this, i create in my index.php inside the div called

<div id="slideHome">
    <div id="total-slider-previous" class="arrow-previous"></div>
    <div id="total-slider-next" class="arrow-next"></div>

after this the page load the slide, i tried to use

<?php if ( $s->is_runtime() ) : ?>
        <div id="total-slider-previous" class="arrow-previous"></div>
	<div id="total-slider-next" class="arrow-next"></div>
<?php endif; ?>

but i had a Fatal error: Call to a member function is_runtime() on a non-object in
