Ratio to third level subtotal

[#1]

I have a pivot table where I calculate ratios of the values to the subtotals.

I was using the following expression to divide each cell by the first subtotal(second level):

count(distinct Person)/count(distinct total <[Dimension1]> Person)

Now I need to group it by 2 dimensions. I need to divide by the second subtotal(third level)

How can I adapt the expression to be used with 2 dimensions?

This way is not accepted:

count(distinct Person)/count(distinct total <[Dimension1]> <[Dimension2]> Person)

You can simply list the dimensions separated by comma's:

count(distinct Person)/count(distinct total <[Dimension1],[Dimension2]> Person)
