How do I get rid of my errors for Schema.org?

[EcommerceSite]

I put the Schema.org data on my item pages and it works great. However, when an item closes it removes the price. It showed an empty price and that causes an error. The site is now programmed to where if an item closes it removes the price component. This was done about 2 weeks ago and it is still showing a lot of errors. Any ideas?

Have you looked in your webmaster tools dashboard for this site? It has a section structured data in your website and shows exactly which structured data has been picked up? Or are the errors showing up there?

Your Offer needs to update the "price" property to sold.  This property field can be either text or number.

The schema supports that, but at the same time I do not think google supports it. If it were me, what I would do is have the offer information in a div around the price. Then when a product was sold I would remove the div so that the product information stayed, but the offer was removed. If you look at the google product rich snippet documentation it says that it only supports a floating point number for price and not text. https://support.google.com/webmasters/answer/146750?hl=en

Alternatively the website could be set to leave the price and use the availability identifier.

Yeah, Google Webmaster Tools is where I found the errors. When I implemented Schema it showed me with about 35,000 items, and about 9000 errors. I came in today and now my errors are almost gone, down to 600 but my total items dropped to 1600. I checked to see if any other code was removed and it wasn't, and ran the Bing Webmaster Tools Validator and it shows everything is correct. Why that drop?

I did exactly what you said but now I am running into this posted above-
