formulation of an expiry summary

[croberts]

I am trying to create a summary sheet in my workbook whic
will show the earliest expiry dates for a particular item. The date
are entered into other worksheets in the workbook and are linked to th
summary worksheet, however the problem that I am finding is that if n
data (date) is entered into a cell under a particular heading on on
of the other worksheets, it is coming up on the summary sheet a
Jan-00. How do I get rid of this ?

The next problem is that I need a formula that will recognise th
earliest expiry date. I have tried the =MIN but because of the curren
problem of it reading no data as Jan-00 it will always read this as th
earliest expiry rather than the actual data entered. What can I do, o
what formula is needed to fix this.


Can you please help me with this, as I am lost for an answer fro
anyone else

Instead of using links like: =Sheet1!A1
put it as: =IF(Sheet1!A1="","",Sheet1!A1)
That should hopefully clear up both issues
