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

IntlDateFormatter::parse - Parse string to a timestamp value

	Object oriented style

SYNOPSIS
public int IntlDateFormatter::parse (string $value, [int &$position]) DESCRIPTION
Procedural style int datefmt_parse (IntlDateFormatter $fmt, string $value, [int &$position]) Converts string $value to an incremental time value, starting at $parse_pos and consuming as much of the input value as possible. PARAMETERS
o $fmt - The formatter resource o $value - string to convert to a time o $position - Position at which to start the parsing in $value (zero-based). If no error occurs before $value is consumed, $parse_pos will contain -1 otherwise it will contain the position at which parsing ended (and the error occurred). This variable will contain the end position if the parse fails. If $parse_pos > strlen($value), the parse fails immediately. RETURN VALUES
timestamp parsed value, or FALSE if value can't be parsed. EXAMPLES
Example #1 OO example <?php $fmt = new IntlDateFormatter( 'en_US', IntlDateFormatter::FULL, IntlDateFormatter::FULL, 'America/Los_Angeles', IntlDateFormatter::GREGORIAN ); echo 'First parsed output is ' . $fmt->parse('Wednesday, December 20, 1989 4:00:00 PM PT'); $fmt = new IntlDateFormatter( 'de-DE', IntlDateFormatter::FULL, IntlDateFormatter::FULL, 'America/Los_Angeles', IntlDateFormatter::GREGORIAN ); ?> Example #2 datefmt_parse(3) example <?php $fmt = datefmt_create( 'en_US', IntlDateFormatter::FULL, IntlDateFormatter::FULL, 'America/Los_Angeles', IntlDateFormatter::GREGORIAN ); echo 'First parsed output is ' . datefmt_parse($fmt, 'Wednesday, December 20, 1989 4:00:00 PM PT'); $fmt = datefmt_create( 'de-DE', IntlDateFormatter::FULL, IntlDateFormatter::FULL, 'America/Los_Angeles', IntlDateFormatter::GREGORIAN ); echo 'Second parsed output is ' . datefmt_parse($fmt, 'Mittwoch, 20. Dezember 1989 16:00 Uhr GMT-08:00'); ? The above example will output: First parsed output is 630201600 Second parsed output is 630201600 SEE ALSO
