How to get updated pricing based on product variation selection?

I posed this question on the FB page and got no response so now I’m posting here. I’m wondering how to get the display price on the product page to update based on variation selection. If I have one product with multiple variations all at varying cost I would like that cost to be accurately displayed once they’ve selected which variation they prefer. Can anyone give me a hand?
