Could you help me understand what I$\text{'}$m doing wrongly?

My SAS codes are:

$*$Reading data in;

Proc import datafile $=\text{'}/$home$/$u$63781314/$Project$/$Project$\_$AD$.$csv$\text{'}$

out$=$mydata dbms$=$csv replace;

getnames$=$no;

run;

$*$print the data to the screen to see if they are okay;

proc print data$=$ mydata;

run;

THIS PART WORKS PERFECTLY

Next codes don't work

$1)$ proc corr data $=$ mydata;

by State;

var Cancer; run;

SAS said that ERROR: Variable CANCER not found.

But my variable name is exactly Cancer.

What I forgot to put in codes? Maybe INPUT with variables names?

Thanks.

How my data set looks like
