IIF Limitation

I am using IIF statement to specify weeks as shown below.
Unfortunately it does not allow me to go beyond 13 weeks.
How can I overcome this limitation?

TrainingWeek: IIf([StartDate] Between #01/May/04# And
#07/May/04#,"Week 1",IIf([StartDate] Between #08/May/04#
And #14/May/04#,"Week 2",IIf([StartDate] Between
#15/May/04# And #21/May/04#,"Week 3",IIf([StartDate]
Between #21/May/04# And #28/May/04#,"Week 4",IIf
([StartDate] Between #29/May/04# And #04/Jun/04#,"Week
5",IIf([StartDate] Between #05/Jun/04# And
#11/Jun/04#,"Week 6",IIf([StartDate] Between #12/Jun/04#
And #18/Jun/04#,"Week 7",IIf([StartDate] Between
#19/Jun/04# And #25/Jun/04#,"Week 8",IIf([StartDate]
Between #26/Jun/04# And #02/Jul/04#,"Week 9",IIf
([StartDate] Between #03/Jul/04# And #09/Jul/04#,"Week
10",IIf([StartDate] Between #10/Jul/04# And
#16/Jul/04#,"Week 11",IIf([StartDate] Between #17/Jul/04#
And #23/Jul/04#,"Week 12",""))))))))))))

Hi,


Use a table.


Trainings ' table name
Name, Starting, Ending ' fields name
"week 1", #05-01-2004#, #05-07-2004#
.... data



then, in the query, bring that table and, under your actual StartDate
(unknown table from your post), add the criteria:

BETWEEN [Trainings].[Starting] AND [Training].[Ending]


add the computed expression:



TrainingWeek: [Trainings].[Name]



Now, not only it is simpler, neat, and faster, it is also "re-usable"
without having to touch any piece of SQL code! since the relevant data is in
a table and end user knows how to change data in a table,... while letting
them touch your SQL code is ... a risk.



Hoping it may help,

As Michel says, a table-driven solution would be ideal; you might also
want to consider the Switch() function - see the online help in the
VBA editor - rather than nested IIF's.

You Could try

Training Week: "Week " & (Format([Start Date],"ww",2)-17)
