Does this help?

Code:
ALERT_VALUE=85
output="$(df /|grep -v block)"
VALUE=$(echo "$output"|awk '{print $5}'|sed s/\%//g)
partition=$(echo "$output"|awk '{print $1}')
if [ $VALUE -ge $ALERT_VALUE ]
then 	echo "Running out of space \"$partition ($VALUE%)\" on $(hostname) as on $(date)" |
	mail -s "Alert: Almost out of disk space on $(hostname)" group_email
fi

Or your way:
Code:
usep=$(echo $output | awk '{ print $1}' | cut -d'%' -f1  ) partition=$(echo $output | awk '{ print $2 }' )

Should be either:
Code:
usep=$(echo $output | awk '{ print $1}' | cut -d'%' -f1  ) 
partition=$(echo $output | awk '{ print $2 }' )

OR
Code:
usep=$(echo $output | awk '{ print $1}' | cut -d'%' -f1  ) ; partition=$(echo $output | awk '{ print $2 }' )

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
