foreach <option> with paypal

I'm having some issues with paypal using foreach inside the select tag. When I use the paypal option tags with normal html (like the one commented out) everything works well and it adds the item to the cart. In the other hand, when I use the foreach loop to echo out the sizes along with the prices it shows well on the website, but then I get this error from paypal: "PayPal cannot process this transaction because of a problem with the seller's website. Please contact the seller directly to resolve this problem."

Here is how my array looks like:

$products = array();

$products[21101] = array(
    "name" => "Facial Wash",
    "img" => "img/img_detailed/facial-wash.png",
    "sizes" => array("30 ml 5.00 EUR", "200ml 25.00 EUR"),
    "paypal" => "XBSERUGPEXHDW"

Here is the paypal form:

<form target="paypal" action="https://www.paypal.com/cgi-bin/webscr" method="post">
                        <input type="hidden" name="cmd" value="_s-xclick">
                        <input type="hidden" name="hosted_button_id" value="<?php echo $product["paypal"]; ?>">
                        <input type="hidden" name="item_name" value="<?php echo $product["name"]; ?>">
                                    <input type="hidden" name="on0" value="Sizes">
                                    <label for="os0">Size</label>

                                    <select name="os0">
                                        <?php foreach($product["sizes"] as $size) { ?>
                                        <option value="<?php echo $size; ?>"><?php echo $size; ?></option>
                                        <?php } ?>
                                    <option value="200ml">200ml 25.00 EUR</option>
                                    <option value="30ml">30ml </option>
                                    <input type="hidden" name="currency_code" value="EUR">
                                    <input type="image" src="https://www.paypalobjects.com/en_US/i/btn/btn_cart_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!">

Remember, when I remove the php code and use the commented out lines, it works great.

Thanks in advance for any help or input.

There are multiple points where things could've gone wrong to generate that error, so I can't tell you exactly where to look. To help you move along, the first step to debug a PHP-generated webpage is to view the page source via your browser's dev tool View Page Source option (safari is command+option+U) and see if the generated HTML is as expected.
