Hi I have query in access  where I have a table that has fields Item, Date Req, Required, Available that is grouped by Item, ordered by  Date Req field.
I like to get a field "Previous use" which will be the previous record value from the required field, except when it doesn't have one for the group, item. For example I like to see the result as follows

Item  Date Req     Required   Available   Previous Use    
Abc   11/1/14         100             600             0          
Abc    11/3/14         200            600             100    
Abc    11/10/14        100           600             300         ( 100 +200  which is  before 11/10/14)
CCC    11/2/14          200           700             0
CCC      11/5/14        300           700            200

I will appreciate if somebody can let me know how I can do this access query.
thanks
