Jet Vs ADO aggregate function difference

just wasted a long time figuring out this and I figure if I post it
might save someone some pain!

Jet (DAO) will allow you to to use nested aggregate functions like
building blocks, e.g.:

sum(B) as Answer1,
Answer1 * 2 as DoubleAnswer

If you save this query and run it from ADO
(e.g. ADORecordset.Op en "qrySavedQuery" , myConnection) you will get:

You tried to execute a query that does not include the specified
expression 'Answer1 * 2' as part of an aggregate function.

Yet opening the saved query normally or calling it from DAO will work

ADO requires you to write the query like this:

sum(B) as Answer1,
sum(B) * 2 as DoubleAnswer

i.e. an aggregate function cannot refer to another aggregate function
in the same query.

Anyone else found this, or am I mis-reading cause and effect of problem

I have an invoice form with Parts and Labor as subforms. The parts section is based on a query that pulls data from 2 tables (tblParts & tblPartPerClaim) .. It has fields: ClaimID: tblPartPerClaim; NET PRICE: tblParts; Quantity: tblPartPerClaim; and a calculated field Part Total: (*). On my subform, I have a text box in the footer that displays the sum of the Part Total field (=Sum(*)). This text box is called PartsClaimed.

I need help writing a function for a program that is based upon the various operations of a matrix and I keep getting a "non-aggregate type" error. My guess is that I need to dereference my pointers, but I'm not sure. Please help. The code: void equate(matrix *A, matrix *B) { int i, j; assert(A.row_dim == B.col_dim && A.col_dim == B.col_dim); for(i=0; i < A.row_dim; i++) for(j=0; j < A.col_dim; j++)
