thanks - seems to be OK now can i ask another question

I have this at the end of a script to interpret the output code correctly

if [ $EXITCODE -eq 0 ]; then
    echo "$OUTPUT" | grep -v CRITICAL
    [ $? -eq 1 ] && EXITCODE=2
fi

but when the script runs i get this

../libexec/retrieve_custom_snmp: line 84: [: -eq: unary operator expected
"CRITICAL emcpowera has 2 dead, 2 alive"

can anyone help with this issue

thanks
