How to Put Product Price into my module

[mechworm]

I want to create a module that shows the product price in the product page tab. With my limited coding and prestashop structure knowledge, I created the module below. Currently, this module works fine and the simple txt html code in "mymodule.tpl" appears in my product page tabs.

The next two steps are

1-Calling product price from database in mymodule.php 

2-Printing this variable through the mymodule.tpl. ( Call productprice variable from mymodule.php and print it).

The problem is that I don't know how to do both. I tried hard but couldn't find a solution. Can someone please help me?

Thanks in advance!
