I made a typo in there sorry, left off a square brack and forgot the keyword "Member".
Yes it's always too early for MDX! Obviously by my error it was too late for MDX too 😉
You're right you only need one "With" at the beggining and then you can list out the calcs
Here's the right one:
With Member [Measures].[Yesterday Clicks] as
(
[Measures].[Click Count]
)
