Using Mail Variables and who for a result

[DeadBeet]

So, I'm trying to email myself when the load of the server is greater than 5. Here is my code, unfortunately, it doesn't work. I Get:

./action: line 8: [: 0.28: integer expression expected


I'm guessing the 0.28 is the current load

#!/bin/bash
load=`w | awk 'NR == 1 {print}' | awk '{print $8}' | sed 's/,//'`;
loadout=$load >> load.out
warn=`echo CPANEL3 LOAD IS:`;
LIMIT=5
# if [ "$load" -gt 0 ] then ;

if [ $load -gt "0" ]
then
echo "$warn $load | mail -s "$warn $load" `cat mail`"
fi

#echo "SYSTEM Load is high" | mail -s "SYSTEM LOAD HIGH '$LOADOUT'" email@email.com < load.out
#echo "SYSTEM LOAD IS:" > load.out |exec w | awk 'NR == 1 {print}' | awk '{print $8}' | sed 's/,//' >> load.out
