Running Total with no Calendar table

[joknoke]

Hi, I need help to create the running total of the third column of the left image. I do not have a calendar table, I just have Year Table on the right side of the image. The measure the third column is
% Countries vs World = DIVIDE([Sum Countries Mhl], [Sum World Mhl])
Pls help

Hi there John, as luck would have it I have an example which showcases exactly how to do this.

Give this a good, it should get you what you need.

Any issues comes back.
