[#1]

Hey , i want to create a listbox for age group.

Ex:

AgeGroup

1-10

10-20

20-30

30-40

40-50

Above 50

I am using:

if

(Age>=10, '1-10',
if(Age>=20, '10-20',
if(Age>=20, '20-30',
if(Age>=30, '30-40',
if(Age>=40, '40-50',
if(Age>=50, 'Above 50')))))) as

AgeGroup

But i am getting:

AgeGroup

1-10

can anybody please tell me what mistake i am doing..........

Please use CLASS!

class( expression, interval [ , label [ , offset ]] )
Creates a classification of expressions. The bin width is determined
by the number set as interval. The result is shown as a<=x<b, where
a and b are the upper and lower limits of the bin. The x can be
replaced by an arbitrary string stated in label. 0 is normally the
default starting point of the classification. This can be changed by
adding an offset.
Examples:
class( var,10 ) with var = 23 returns '20<=x<30'
class( var,5,'value' ) with var = 23 returns '20<= value <25'
class( var,10,'x',5 ) with var = 23 returns '15<=x<25'
