Order_Count seems to be a aggregation. These are enabled in your query design
by selecting View->Totals. This will aggregate your records and generally
require setting the Total: row in the query to something like Group By,
Count, Sum, or Avg.
If you want a new column created that performs calculation, you enter the
expression into a new blank column in the grid. Your expression might look
like:
Order_Count: {your expression here]
You might want to search the web for SQL QUERY SYNTAX.
