For storing the value, try this
Code:
b=`chktraf -s | cut -c1-4`

or
Code:
b=$(chktraf -s | cut -c1-4)

And if loop doesn't work, reason as gary_w said, space is the issue
Code:
if [ $b -eq 0 ]
then
  ...
fi

err_get_lib

ERR_GET_LIB(3)							      OpenSSL							    ERR_GET_LIB(3)

NAME

       ERR_GET_LIB, ERR_GET_FUNC, ERR_GET_REASON - get library, function and reason code

SYNOPSIS

	#include <openssl/err.h>

	int ERR_GET_LIB(unsigned long e);

	int ERR_GET_FUNC(unsigned long e);

	int ERR_GET_REASON(unsigned long e);

DESCRIPTION

       The error code returned by ERR_get_error() consists of a library number, function code and reason code. ERR_GET_LIB(), ERR_GET_FUNC() and
       ERR_GET_REASON() can be used to extract these.

       The library number and function code describe where the error occurred, the reason code is the information about what went wrong.

       Each sub-library of OpenSSL has a unique library number; function and reason codes are unique within each sub-library.  Note that different
       libraries may use the same value to signal different functions and reasons.

       ERR_R_... reason codes such as ERR_R_MALLOC_FAILURE are globally unique. However, when checking for sub-library specific reason codes, be
       sure to also compare the library number.

       ERR_GET_LIB(), ERR_GET_FUNC() and ERR_GET_REASON() are macros.

RETURN VALUES

       The library number, function code and reason code respectively.

SEE ALSO

       err(3), ERR_get_error(3)

HISTORY

       ERR_GET_LIB(), ERR_GET_FUNC() and ERR_GET_REASON() are available in all versions of SSLeay and OpenSSL.

0.9.7d								    2002-04-30							    ERR_GET_LIB(3)
