Count if X equals LastMonth

[Anonymous]

Hi,

I want to implement something like

count({<[WorkMonth]=Month(Today())-1>} WorkItem)

WorkMonth is a column represents the month, in which WorkItem was done.

But its a wrong expression. How can I do this?

Thanks a lot.

Try

=Count({<[WorkMonth]={"$(=Month(Today())-1)"}>}WorkItem)
