Format Variable Error

[MisterJenn]

I keep getting this error but I don't understand why. I formatted  the variables beforehand so I should be able to do a procprint using those formatted variables. 

libname hw4 '\\apporto.com\dfs\GWU\Users\kennedyhinnant_gwu\Downloads\Assignment 4';
data fit1;
set hw4.fit1;
run;
*Question (i-iv);
proc format; 
value CSfmt 1 = 'Current Smokers' 0 = 'Nonsmokers';
value txfmt 1 = "treatment" 0 = "Placebo";
value bmifmt 25-HIGH ="overweight" LOW -< 25="normal";
value bmigrp LOW -< 18= 'underweight' 18 - 25 = 'normal' 25 <- HIGH = 'normal';
run;
proc means data =fit1 p25; 
*Quesition 1(v-vi);
proc format; 
value cobmdfmt 0.545-HIGH = 'Above';
value blbmdfmt LOW -< 0.542 = 'less'; 
run;
*Question 1(c);
data fit1tmp;
set hw4.fit1;
run;
*Question 1c(ii); 
proc print data=fit1(obs=5);
var dob dov;
format dob dov mmddyy10. smoker CSfmt. tx_status txfmt.;
run;
*Question 1c(iii); 
proc print data=fit1(obs=5); 
var dob dov Csfmt. txfmt.;
run;

Formats have to be assigned in FORMAT statement. You can not do that in the VAR statement.

And you must close the table viewer before you run the code.
