Executing Query

Hi there,

I am trying to run a query from an ASP page, which also uses other queries. I get the following error message: [Microsoft][ODBC Microsoft Access Driver] You tried to execute a query that does not include the specified expression 'Expr1' as part of an aggregate function, this is in qrySessionsEverything.


The query name is qrySessionsEverything.
It executes the line:

SELECT * FROM qrySessionsEverything

The queries are below:

qrySessionsEverything
