Unique Cumulative Total Question

Hi community,

I’m just not sure how to calculate the cumulative total here.

I’ve tried many different variations on this, including change the date column, different functions etc.

I’ve spent so much time on this, not sure why it’s not working for me.

Some help would be really appreciated

I would be great if we actually could see the formula you are using to assist further here.

Here’s is some tutorial examples to review.

Also have a look through these ones also

Plenty to learn by working through these.
