Here would be the structure:

IF(K# > =65)

THAN

D# = "65 and Older"

ELSE

IF(K#<=64 && K#>=55)

THAN

D# = "55-64"

ELSE

IF(K#<=54 && K#>=45)

THAN

D#="45-54"

ELSE

IF(K#<=44 && K#>=35)

THAN

D#="35-44"

ELSE

IF(K#<=34 && K#>=25)

THAN

D#="25-34"

ELSE

IF(K#<25)

THAN

D# = "Younger than 25"

Can someone write this up because I have tried numerous times to write this.
