Using tooltips with EuroFx Currency Shortcode inside

I’m creating an ACT tooltip. The content is a shortcode from EuroFx currency converter. I’m going to use the ACT Tooltip shortcode on a page to convert the price of a Woocommerce product form Euros to Reais and Dollars.
The shortcode I’m placing inside the tooltip is:
[currency amount=”300″; from=”EUR” to=”BRL” show_from=false converts to ” append=”” round_append=””].

It works perfectly if I write the “currency amount”, but what I’m trying to do is to replace the value in that field with something that actually gets the Woocommerce product price from the page where the tooltip shortcode is written.

I was trying to use get_post_meta( get_the_ID(), ‘content’, true), but to no avail.

Is this possible at all?
