I'm trying to figure out how to start adding rich snippets to products but I keep getting an error from Google stating:In order to generate a preview with rich snippets, either price or  review or availability needs to be present.But I have price in there in a meta tag. I don't get what's wrong here:<li itemprop=offerDetails itemscope itemtype=http://data-vocabulary.org/Product class=span3>    <div class=thumbnail><meta itemprop=category content=flowers>        <a itemprop=url href=/en/2-in-too-deep.html title=Depth>            <img itemprop=image alt=A dozen red roses is as romantic as it is classic. src=/2-441-catalog/.jpg>            <meta itemprop=description content=[A dozen red roses is as romantic as it is classic.]>        </a>        <div class=caption_mobile visible-phone><p itemprop=name>Depth</p></div>    </div>    <div class=caption hidden-phone>        <h4 itemprop=alternateName>Depth</h4>        <meta itemprop=price content=&#36;40>        <meta itemprop=currency content=USD />    </div></li>
Google stating price is missing from product rich snippet, but it is present
google search console;rich snippets
