jQuery Functions not executing properly

I have three <ul>'s which I want to merge and turn into a slider (I'm using the bxslider). It is something like...

<div class="wrapper">
    <ul class="products-grid">
        <li>Product 1</li>
        <li>Product 2</li>
        <li>Product 3</li>
    </ul>
    <ul class="products-grid">
        <li>Product 4</li>
        <li>Product 5</li>
        <li>Product 6</li>
    </ul>
    <ul class="products-grid">
        <li>Product 7</li>
        <li>Product 8</li>
        <li>Product 9</li>
    </ul>
</div>

When I execute the below lines of jQuery in the chrome console, one line at a time, everything works perfectly.

jQuery('ul.products-grid').children('li').appendTo('ul.products-grid:first'); 
jQuery('ul.products-grid').not(':first').remove(); 
jQuery('ul.products-grid').bxSlider({
    slideWidth: 200,
    minSlides: 1,
    maxSlides: 3,
    slideMargin: 10
});

But when I try to execute the jQuery in the php/html template or in the chrome console all at once, only the first line executes and I'm left with...

<div class="wrapper">
    <ul class="products-grid">
        <li>Product 1</li>
        <li>Product 2</li>
        <li>Product 3</li>
        <li>Product 4</li>
        <li>Product 5</li>
        <li>Product 6</li>
        <li>Product 7</li>
        <li>Product 8</li>
        <li>Product 9</li>
    </ul>
    <ul class="products-grid">
    </ul>
    <ul class="products-grid">
    </ul>
</div>

Any idea how I can fix this? It seems to have something to do with the order in which the code is executing.

UPDATE

I noticed that in the console if I put the debugger on just before the code executes I get the below error after the

Uncaught ReferenceError: optionsPrice is not defined    bundle.js 110

reloadPrice: function() {
    var calculatedPrice = 0;
    var dispositionPrice = 0;
    var includeTaxPrice = 0;
    for (var option in this.config.selected) {
        if (this.config.options[option]) {
            for (var i=0; i < this.config.selected[option].length; i++) {
                var prices = this.selectionPrice(option, this.config.selected[option][i]);
                calculatedPrice += Number(prices[0]);
                dispositionPrice += Number(prices[1]);
                includeTaxPrice += Number(prices[2]);
            }
        }
    }

    var event = $(document).fire('bundle:reload-price', {
        price: calculatedPrice,
        priceInclTax: includeTaxPrice,
        dispositionPrice: dispositionPrice,
        bundle: this
    });
    if (!event.noReloadPrice) {
        optionsPrice.specialTaxPrice = 'true';  // line 110
        optionsPrice.changePrice('bundle', calculatedPrice);
        optionsPrice.changePrice('nontaxable', dispositionPrice);
        optionsPrice.changePrice('priceInclTax', includeTaxPrice);
        optionsPrice.reload();
    }

    return calculatedPrice;
},
