The problem must be solved without using VB and the excel version is 2003 !

The problem is I have an everyday sheet to keep track of some part#s and
another that need to take the data from that day and place them under that
day in a sheet that keeps track of data for a week at a time.
I got a field on the latter that updates the day using date functions and
from which I derive the actual day.

i need to do something like:

IF(THISDAY="TUESDAY";a2=[dailysheet]!a2; ....else keep the data alreayd in a2)

where the problem is the latter part since writing ;) or ;"") clears the
field and ;a2=a2) gives circular ref. error.

also if the current day is friday all the previous 'day'-fields must contain
their values until I set a field on a formula sheet to 'ClearAll',

like IF([formulas]g10="ClearAll";"";IF(THISDAY.........))

Latter construction works fine and, but I still need a way to retain cells
with their values if they are not updated.

Any ideas?....without using VB!
