[MarketPress eCommerce] Marketpress product price meta tag for revolution slider

I currently have a Revolution Slider product carousel located on the main store sidebar. This is a post-based slider which automatically adds and removes the products it displays depending on the criteria i set.

Each slide uses 'meta tags' to get and display the information relating to each slide. I currently just use {{title}} which displays the product title of each product, but i want to display the product price to be displayed also. I cant seam to achieve this. If i use a shortcode such as [mp_product_price] & [mp_product_price product_id="7045"], but it simply displays a single product price and doesn't actually get the product price data of the active slider being displayed.

I hope this makes sense, any help would be great.
