Need help creating calculated member that allows me to exclude some components

Hi Lauma! We are looking to have issue 4 show up.
This is what i have so far:
Under the projects Calculated members

Aggregate(
Except(
[Project].[Component].Members,
{
[Project].[Component].[A],
[Project].[Component].[B]
}
))

But issues with A B C, still show up on the table.
