Parsing the output from top

Guys can you help me fix this parse error.

Here's my script.

Code:

#!/bin/bash
# Set up limit below

NOTIFY="6.0% us 6.1% us 6.2% us 6.3% us 6.5% us 6.6% us 6.7% us 6.8% us 6.9% us 7.0% us"

# CPU Usage every minute
TOP="$(top -b -n2 -d 00.20 |grep Cpu|tail -1 | awk -F ":" '{ print $2 }' | cut -d, -f1)"

# compare it with last usage
RESULT=$(echo "$TOP > $NOTIFY" | bc)

# if load >= 80.0% create a file /home/scripts/loadavg.txt

if [ "$RESULT" = "6.0% us 6.1% us 6.2% us 6.3% us 6.5% us 6.6% us 6.7% us 6.8% us 6.9% us 7.0% us" ]; then
        echo $RESULT "cpu usage" >>  /home/scripts/loadavg.txt

This will output the cpu usage then compare on the notify now i'm getting this error

Code:

-bash-3.00$ sh -x cpu 
+ NOTIFY='6.0% us 6.1% us 6.2% us 6.3% us 6.5% us 6.6% us 6.7% us 6.8% us 6.9% us 7.0% us'
++ top -b -n2 -d 00.20
++ grep Cpu
++ tail -1
++ awk -F : '{ print $2 }'
++ cut -d, -f1
+ TOP='  6.7% us'
++ echo '  6.7% us > 6.0% us 6.1% us 6.2% us 6.3% us 6.5% us 6.6% us 6.7% us 6.8% us 6.9% us 7.0% us'
++ bc

Thanks in advance.

cs_render

cs_render(3)							      cs/cs.h							      cs_render(3)

NAME

       cs_render  - render a CS parse tree

SYNOPSIS

       #include <cs/cs.h>

       NEOERR *cs_render (CSPARSE *parse, void *ctx, CSOUTFUNC cb);

ARGUMENTS

       parse - the CSPARSE structure containing the CS parse tree
       that will be evaluated
       ctx - user data that will be passed as the first variable to
       the CSOUTFUNC.
       cb - a CSOUTFUNC called to render the output.  A CSOUTFUNC is
       defined as:
       typedef NEOERR* (*CSOUTFUNC)(void *, char *);

DESCRIPTION

       cs_render  will evaluate a CS parse tree, calling the CSOUTFUNC passed to it for output.  Note that calling cs_render multiple times on the
       same parse tree may or may not render the same output as the set statement has side-effects, it updates the HDF data used  by  the  render.
       Typically, you will call one of the cs_parse functions before calling this function.

RETURN VALUE

       None
