Reference a CTE From Another CTE

Can I use a CTE inside another CTE?

I created CTE_1, tested, works
I created another CTE Using CTE_1 as the source table, but I get error 'unexpected CTE_2'

Any ideas?
Thanks

Yes.


;WITH cte1 AS (
    SELECT ...
    FROM dbo.sometable
),
cte2 AS (
    SELECT ...
    FROM cte1
),
cte3 AS (
    SELECT ...
   FROM cte2
) ...

Thanks - what I thought
Any clues what might be wrong I keep getting error message "unexpected 'cte_product'"
The 1st CTE works as expected.

Thanks

Missing comma between CTEs.

That big, red abomination is supposed to be a comma.
