Hi,
I've read quite a few of the posts up here already and I seem to have a
mixture of problems and solutions, but none quite fit. So I 'm hoping
someone'll pick up and give me the light bulb on this one.

I have a query (qryOutputGrade), it calculates the standard deviated grade
from a set of class average scores. Fields = Subject_Set, Pupil_Code, StdDiff
and Attain.

I want to update my table (of assesments), tblPrepAssessments, to have the
field GRADE_1 updated to hold the Attain grade from qryOutputGrade, based on
the fact that tblPrepAssessments.Pupil_Code=qryOutputGrade.Pupil_Code AND
tblPrepAssessments.Subject_Set=qryOutputGrade.Subject_Set.

There are blanks in the qryOutputGrade.Attain field as not all scores have
been collected yet.

I've tried the following in QBE:
UPDATE qryPrepAssessments, qryOutputGrade SET qryPrepAssessments.GRADE_1 =
[qryOutputGrade]![Attain]
WHERE (([qryPrepAssessments]![PUPIL_CODE]=[qryOutputGrade]![PUPIL_CODE] And
[qryPrepAssessments]![Subject_Set]=[qryOutputGrade]![Subject_Set]));

this runs a result in the QBE pane, but when trying to use the Run command
gives the following error:
"Operation must use an updateable query"

Have also tried this:
UPDATE qryPrepAssessments, qryOutputGrade SET qryPrepAssessments.GRADE_1 =
[qryOutputGrade]![Attain]
WHERE (([qryPrepAssessments]![PUPIL_CODE]=[qryOutputGrade]![PUPIL_CODE] And
[qryPrepAssessments]![Subject_Set]=[qryOutputGrade]![Subject_Set]));

or is there any other way of doing this? Thanks for your help, greatly
appreciated.

Wendy
