Test if Sum of Revenue by Account is more than 10K

[#1]

I create a new dimension in a pivot table. I would like a different behavior depending on whether the sum of revenues over Accounts is more or less than 10K. For now I came up with

If(AGGR(SUM(Revenue),[Account])>10000,'More','Less')

Which seems not to be working...

What is the correct syntax ?

Account is a dimension in the pivot table.

Can u share your application? Format of Aggr() depends on the no. of dimensions used.
