MS Access 2010 Date help

Hi
Need help with the following please.
We have a query that contains a date field. What we cant to do is add 7 days to this date and then show the last 30 days from today.
So for example I have the following

Date in Table           Add 7 Days      
01/09/2014              08/09/2014
01/12/2014              08/12/2014
02/12/2014             09/12/2014

I can get the query to add 7 days and show the correct date, but I also then want the query to only show me records that have a date from today 30 days back based on the new date I have created, so from the example above the would only return 2 records that have a date in December.  I cant seem to do that as I can seem to add a query to the field that creates the new date, If I try and then run the query I get the "enter parameter value"

Thanks

It would help if you'd show the SQL of your query.

Adding 7 days is straight forward:

SELECT Field1, DateAdd("d", 7, YourDateField) AS NewDate FROM SomeTable

This would create a column named NewDate in the query, and would add 7 days to a field named YourDateField.

If you then want to query and filter on YourDateField for values starting at 30 days in the past:

SELECT YourDateField, DateAdd("d", 7, YourDateField) AS NewDate FROM SomeTable WHERE YourDateField >= DateAdd("d" , -30, Now)
