IMHO = In My Humble Oppinion
Which I thought to be a "normal" internet acronym?
Again I would use a table... probably... unless you are REAL sure you wont need this list anywhere else... Then again... it could be real simple like...
1) Table
Create a table which contains values 0,1,2,3,4,5,6
2) Query
Base your listbox on this query,
Select date() - [column_from_above_table] as last_days from [above_table]
order by date() - [column_from_above_table]
That should allways populate your listbox with the last 7 days, simply add 7,8,9,10,etc as needed...
Short, simple, easy and no messing with listboxes...
