If condition error

[Sathish_jammy]

i tried up whith this condition.

But the 89 series are come up as null ... Why?

data cre_epi;
set creatin7;
if epi_1 ge 90 then  
	epi_1_stage =1; 
if epi_1 ge 60 and epi_1 le 89 then 
	epi_1_stage =2; 
if epi_1 ge 30 and epi_1 le 59 then 
	epi_1_stage =3; 
if epi_1 ge 15 and epi_1 le 29 then 
	epi_1_stage =4; 
if epi_1 lt 15 then 
	epi_1_stage =5; 
if epi_1 =. then 
	epi_1_stage =.; 
if epi_5 ge 90 then
	epi_5_stage =1;
if epi_5 ge 60 and epi_5 le 89 then 
	epi_5_stage =2; 
if epi_5 ge 30 and epi_5 le 59 then 
	epi_5_stage =3; 
if epi_5 ge 15 and epi_5 le 29 then 
	epi_5_stage =4; 
if epi_5 lt 15 then 
	epi_5_stage =5; 
if epi_5 =. then 
	epi_5_stage =.; 
run;

mno	epi_1	epi_5	epi_1_stage	epi_5_stage
124438	75.387	89.875	2	.
124412	82.071	82.071	2	2
112956	89.944	.	.	.

Very simple. 89.875 is NOT less or equal to 89.

Use this type of conditions:

if epi_1 ge 60 and epi_1 lt 90 then 

[PaigeMiller]

The value of 89.875 doesn't satisfy any of your conditions. It is not greater than 90. It is not between 60 and 89. etc.

This looks more like a job for formats anyways. 

proc format;
  value creatin
    1-15=5
    15-30=4
    30-60=3
    60-90=2
    90-high=1
    other=.;
run;

data want;
  set have;
  format epi_1 epi_5 creatin.;
run;
