Code:
#!/bin/ksh
set -x
#building regex for date searching
regex="${yr_mnth}[0-9][0-9]"
# where's $yr_mnt defined?

#building date searching regex list file
xtr_regex="${xtr_flptrn1}${inst_nmb}-${regex}.${list_file}"
#where are xtr_flptrn1  nst_nmb list_file defined?
# placing {} for possible variable names - validate

 cmptl_extr_list_file="${xfile_pth}/${xtr_regex}"  #storing complete file name with path into a variable

#echo $cmptl_extr_list_file

#grepping the filename from list file
/bin/grep '$flnm_80BYTE' $cmptl_extr_list_file
# as noted don't use single quotes - they will hide the variable expansion 
# /bin/grep "${flnm_80BYTE}" ${cmptl_extr_list_file}"

edited code (edits/questions in red) - for possible variable name spec changes - validate the placement of {}'s
Enabled set -x to aid in debugging

zgrep

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
