I have a workbook setup with tabs for each month named "Jan 07", "Feb 07" etc.
In each tab, vertically the days of that month form the top-left of a range
going some 20 columns right and about 8 rows down. Then an empty row and the
next day is up. Picture it?

Ok, now what I can't get done is to get the data of a specified date to
another worksheet (in the same workbook). Simply to represent what's been
entered on a date and to do some more calculations.

What I got so far is: =OFFSET(INDIRECT("'"&-SheetName-&"'!-reference-");;2)
-SheetName- is a cell with the name of the tab to look at.
-reference- is the issue.
I need Excel to lookup the cell where the requested daterange starts in
order to get OFFSET get the data. I can't find a way to do that with a
VLOOKUP...

Please help! It's highly appreciated!
