Let's say I've got a table like this

[![enter image description here](https://i.stack.imgur.com/MH7rH.png)](https://i.stack.imgur.com/MH7rH.png)

What I want to do is get a formula that always gets the last value in column B and put it on cell D1, so in this case I want to get the value "21" but then if I keep adding values to this list I want to always get the value placed in the last row on that list. is there a way to do this?
