Help with database checking script

I haven't coded in ksh in forever and this script is proving me not a great coder. I keep getting unexpected end of file when I try to execute this...Line 94 is the last line of the code..

#!/usr/bin/ksh
. /home/oraprod/.bash_profile
DBSID=prod # Database sid
CONNECTSTR=apps/xxxxxxxx@prod # Connect string prod
MAILADR=dba@group.com # mail
ACCEPTLAG=2 # allowed difference

# set the environment to the standby database
export ORACLE_SID=prod
export ORACLE_HOME=/u02/app/proddb/10.1.0.5
export PATH=$PATH:$ORACLE_HOME/bin
# declare functions to query v$archived_log and other checks

runsqlstb()
{
sqlplus -S <<EOF
/ as sysdba
set heading off
select max(sequence#) from v\$archived_log where applied='YES' and dest_id=2 ;
exit
#EOF
}

runsqlprd()
{
sqlplus -S ${CONNECTSTR} <<EOF
set heading off
select max(sequence#) from v\$archived_log;
exit
# EOF
}

mailme()
{
if [ ${LAGDIFF} -gt ${ACCEPTLAG} ]
then
echo
echo The ${DBSID} standby database lacks behind too far.
echo logseq ${DBSID} production database is $NUMBERPRD >> mailtempl
echo logseq ${DBSID} standby database is $NUMBERSTB >> mailtempl
echo
mailx -s "Standby database out of sync " ${MAILADR} < mailtempl
rm mailtempl
fi
}

errtrap()
{
#echo Fout in script > mailtempl
mailx -s "Fout in script " ${MAILADR} < mailtempl
rm mailtempl
}

NUMBERSTB=`runsqlstb`

then

NUMBERPRD=`runsqlprd`
if [ $? -ne 0 ]
then

echo standby database is ${NUMBERSTB}
echo production database is ${NUMBERPRD}

NAME
escape - escape shell special characters in a string SYNOPSIS
escape string DESCRIPTION
escape prepends a "" character to all shell special characters in string, making it safe to compose a shell command with the result. EXAMPLES
The following is a contrived example showing how one can unintentionally end up executing the contents of a string: $ var='; echo gotcha!' $ eval echo hi $var hi gotcha! $ Using escape, one can avoid executing the contents of $var: $ eval echo hi `escape "$var"` hi ; echo gotcha! $ A less contrived example is passing arguments to Mail Avenger bodytest commands containing possibly unsafe environment variables. For example, you might write a hypothetical reject_bcc script to reject mail not explicitly addressed to the recipient: #!/bin/sh formail -x to -x cc -x resent-to -x resent-cc | fgrep "$1" > /dev/null && exit 0 echo "<$1>.. address does not accept blind carbon copies" exit 100 To invoke this script, passing it the recipient address as an argument, you would need to put the following in your Mail Avenger rcpt script: bodytest reject_bcc `escape "$RECIPIENT"` SEE ALSO
avenger(1), The Mail Avenger home page: <http://www.mailavenger.org/>. BUGS
escape is designed for the Bourne shell, which is what Mail Avenger scripts use. escape might or might not work with other shells. AUTHOR
