How to get value for cell based on relative position

New Contributor

Is there a way to get the value of the cell that is 1 row above and 1 column to the left of the cell?

I have a cube view with 2 columns, one is for actuals and the other is for estimate months. The actual column is going to pull the account value directly, but the estimate column needs to pull in the starting balance and then make adjustments. 

Below is an example of the data:



The 'Last Month Ending Balance' row is where I am having an issue and tried to use variables such as |CVSubPeriodPrior| but I get the same value for all of the estimate months. Is there a better variable to use or could I use a simple offset formula to pull in the value of the cell 1 row above and 1 column to the left?
