I just wondered if it was possible to check time availavilty within a
spreadsheet.

For example. I have the following data
Date Start Time End Time
5/2/03 09.00 11.00
5/2/03 13.00 15.30
5/2/03 15.00 16.00

For the 3rd entry I would like to display an error as there is already a
meeting scheduled for this time.

I have asked this before, but maybe wasn't very clear in what I required, as
I had no responses. If there is no way to do this, many thanks for taking
the time to read this post. If there is possbly another way I could work
this please let me know, any help would be greatly appreciated.

Many Thanks

In this set up you can add a formula in cell D3 as follows:

=IF(B3=quot;quot;,quot;quot;,IF(B3lt;C2,quot;ERRORquot;,quot;quot;))

and copy it into D4 (and downwards). I have assumed you have a row of
headings, so you actually want to check from the second entry onwards.

Hope this helps.

PetePut this is the second data row and copy down

=IF(OR(SUMPRODUCT(--($B$2:B2lt;=B3),--($C$2:C2gt;B3))gt;0,SUMPRODUCT(--($B$2:B2lt;=C
3),--($C$2:C2gt;C3))gt;0),quot;Errorquot;,quot;quot;)

Assuming you have dates in column A from A2 down and the start times are
from B2, end times from C2

you could use this formula in D2 and copy down column

=IF(SUMPRODUCT(--(A$1:A$10 B$1:B$10lt;A1 B1),--(A$1:A$10 C$1:C$10gt;A1 B1)),quot;oops!quot;,quot;quot;)--

View this thread: www.excelforum.com/showthread...hreadid=506994I have tried that formula, but it appears to show quot;oops!quot; in valid times, and
not in invalid ie the 8/1 doesn't show oops?

Please advise.

DateStartEnd
01-Jan09.1510.00
02-Jan16.0017.00oops!
03-Jan09.0015.15
03-Jan14.0016.00oops!
05-Jan12.0013.00oops!
06-Jan09.0011.00oops!
06-Jan17.0018.00
08-Jan11.0011.30
08-Jan11.0011.30

I tried the following formula but I have errors on Valid rows.

Please help.

DateStartEndTime Check
01-Jan09.1510.00
02-Jan16.0017.00
03-Jan09.0015.15Error
03-Jan14.0016.00Error
05-Jan12.0013.00Error
06-Jan09.0011.00
06-Jan17.0018.00Error

I would only expect to see the error on rows 3 and 4.
I have entered this into cell d2 and copied this down is this incorrect?

Many Thanks
