Error Detected - PayPal

I'm having trouble with adding items to the shopping cart on PayPal. It worked a few days ago but now when I add an item, it gives me the folllowing:

Some required information is missing or incomplete. Please correct your entries and try again.

So I've gone back and dbl checked my product ID's. They are correct. I've redone the code for the submit items and they are correct. I cant quite figure out why I'm getting this error message.

As a side note I'm in PHP Stage 5 and I've gone ahead and created a paypal account. but some of the screen shots that Randy has shown dont exactly match what is currently on PayPal. I can figure that out easily enough but I didnt know if that added to the discussion.

My gut tells me its something to do with target="paypal" or the method="post"

<?php include("inc/products.php");

$product_id = $_GET["id"]; $product = $products[$product_id];

$section = "shirts"; $pageTitle = $product["name"]; include("inc/header.php");?>

    <div class="section page">
        <div class="wrapper">
            <div class="breadcrumb"><a href="shirts.php">Shirts</a> &gt; <?php echo $product["name"]; ?></div>
            <div class="shirt-picture">
                    <img src="<?php echo $product["img"]; ?>" alt="<?php echo $product["name"];?>" >

            <div class="shirt-details">

                <h1><span class="price">$<?php echo $product["price"]; ?></span><?php echo $product["name"]; ?></h1>
                    <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 $product["paypal"]; ?>"> 
                        <input type="hidden" name="item_name" value="<?php echo $product["name"]; ?>">
                                        <input type="hidden" name="on0" value="Size">
                                        <label for="os0">Size</label>
                                        <select name="os0" id="os0">
                                            <option value="Small">Small </option>
                                            <option value="Medium">Medium </option>

                        <input type="submit" value="Add to Cart" name="submit">
                <a class="shirt-designer">*All Shirts are designed by Mike the Frog</a>  

<?php include("inc/footer.php");?>

on the line that says the following:

<input type="hidden" name="hosted_button_id" value="<?php $product["paypal"]; ?>"> 

you want top add an echo statement, as follows

  <input type="hidden" name="hosted_button_id" value="<?php echo $product["paypal"]; ?>">
