Hi Mynda

I am having a similar problem, the error is: " Expression.Error: We cannot apply operator < to types Table and DateTime"

The code is below.  I am trying to insert a dynamic date range filter into the query by using two "helper queries" called "StartDate" and "EndDate" (see the # FilteredRows3 line)  I have also ensured that these queries return DateTime type but to no success.

Your assistance will be appreciated.

Another question, how do we turn on the suggested syntax display in the Advanced Editor?
