I get this error everytime I run my query. I am basically trying to
copy a field from one query to a table (the query and the table are
joined by a unique ID). This is my SQL:

UPDATE Staff INNER JOIN [Grade Calculator] ON Staff.EmployeeID=[Grade
Calculator].StaffID SET Staff.1stQuarterGrade = [Grade
Calculator].[1stQuarterCalc];

Does anyone know why I would be getting this error? Thanks for your
help.

I would guess that [Grade Calculator] is a Totals query, or has some
totals operator such as Sum, Count, Avg etc. No Totals query nor any
query including a Totals query is ever updateable.

If you can calculate the 1stQuarterGrade (using this query?) at any
time, generally you *should* just calculate it. Storing the grade in
your table risks data validity errors if any of the fields that went
into the calculation ever get edited - if they do, you'll have a
stored grade WHICH IS WRONG and no indication of that fact. Worse, the
stored grade could be edited, innocently or maliciously, giving no
indication that it's been raised or lowered.
