Hello 

I'm currently setting up a new site and have run into a problem where I get a 500 server error when using the html api. we are using TC v2.1.2 but it also happens with 2.1.1 on Umbraco v6.0.5  The form used to submit is  

<form  action="/base/TC/FormPost.aspx" method="post">
    <p class="price">&pound;19.16</p>
    <div class="addArea">
        <select name="quantity" id="quantity" class="pretty dk">
            <option value="1">1</option>
        </select>
        <input type="hidden" name="productid" value="1527"/>
        <input name="AddOrUpdateOrderLine" value="productIdentifier : productid, quantity : quantity" type="hidden"/>
        <input name="storeId" value="1" type="hidden" />
        <input type="submit" name="btnAdd" id="btnAdd" class="addToBasketButton" value="Add to Basket" />
    </div>
</form>

(this was copied from a working site)

The error is shown below
