Unable to sort by rows, syntax error

Hello I want to sort by Status - Blocked, InTest, InDev and InReview. I tried following but it gives me error
Aggregate ({
[Status.Category].[In Progress].[Blocked]
[Status.Category].[In Progress].[In Test]
[Status.Category].[In Progress].[In Dev]
[Status.Category].[In Progress].[In Review]

Error is syntax error at line 3, column1, token [status.category]

The problem with the syntax is that you need to provide the comma separated list of members for the Aggregate function:
