Deleting Criteria

I included a Sample Database.
 Problem is the Delete query.  When I view it gives the right information.
But when I hit Run  it states “Specify the table containing the records you want to delete.  Everything  I TRIED AS NOT WORKED.
The Records need to delete out table ‘CMTS_Daily_Extract and the MinTime Taken only leaving the Max Time.

This is the criteria :WHERE (([CMTS_Daily_Extract]![TakenTime]=[DupsWithOnlyMINTime]![TakenTime]));

SQL View: DELETE CMTS_Daily_Extract.CMTID, CMTS_Daily_Extract.TakenTime
FROM CMTS_Daily_Extract, DupsWithOnlyMINTime
WHERE (([CMTS_Daily_Extract]![TakenTime]=[DupsWithOnlyMINTime]![TakenTime]));

I greatly appreciate any help!

The query doesn't include a specific join so it is creating a Cartesian Product which is NOT updateable.

Try
SQL View: DELETE CMTS_Daily_Extract.*
 FROM CMTS_Daily_Extract Inner Join DupsWithOnlyMINTime
 ON (([CMTS_Daily_Extract]![TakenTime]=[DupsWithOnlyMINTime]![TakenTime]));

If that doesn't work, it is because of the aggregation in the Dups query.  A subselect might work so you can try that.  If nothing else works to make the query updateable, then you need to create a temp table to hold the dups and join to that instead of to the query.  Most of the time, you should avoid temp tables like the plague.  Use them only if you start with a large number of rows and through lots of manipulation end up with a few rows and you need to use the result set more than once OR as in this case if your action query must join to aggregated data and that is making the query non-updateable.

It did not work . Error "join Expression not supported "ON [CMTS_Daily_Extract]![TakenTime]=[DupsWithOnlyMINTime]![TakenTime]"

Rather than trying to debug the syntax with our eyes, build the query using the QBE.  

Add both tables.
Draw the join line.
Change the query type to Delete.

try this query, copy and paste

DELETE CMTS_Daily_Extract.*
FROM CMTS_Daily_Extract
Where exists(select DupsWithOnlyMINTime.TakenTime From DupsWithOnlyMINTime where DupsWithOnlyMINTime.CMTID=CMTS_Daily_Extract.CMTID And DupsWithOnlyMINTime.TakenTime=CMTS_Daily_Extract.TakenTime)
