calculating a formula for a service level

[Andy B]

I am trying to calculate the difference between one cell and another - both
having dates in, to establish if a service level is being achieved for
completing a task.

eg. B2 = 25/6/07 and L2 = 30/6/07 (5 days)

currently if there is no date in L2, it will say "open call" - indicating
that it has not been completed.

the calculation used currently is =IF(ISERROR(DAYS360(B2,L2,TRUE)),"Open
Call",DAYS360(B2,L2,TRUE)) however this does not show working days taken to
complete the call, which is key to the measurement.

Can anybody help please?

Andy,

Try this:-

=IF(L2="","Open Call",L2-B2)

Format as general. It assumes L2 will always be a later date then B2 or blank.

Have you looked at NETWORKDAYS(), rather than DAYS360() ?

Thanks Mike - unfortunately it still includes the weekend days - can I
include the WEEKDAYS or NETWORKDAYS formula in this somehow? thanks

Thanks David - tried that one - it changes the cell to "Open Call" for some
reason?

I can't guess what your problem is unless you tell us the formula you're
using and what the values are in the relevant cells. Are you sure you've
got real dates and not text values? What value does =L2-B2 (or whatever the
relevant cells are) give? And if you are getting an error flagged by
ISERROR(), then you need to look at what specific error the formula inside
the function gives.

Try

=IF(L2="","Open Call",NETWORKDAYS(B2,L2))
