32-bit chroot failed to start

I was going about the process to set up the 32-bit chroot so I could use Adobe Acrobat on my system, but systemctl failed to start the service. Output of "systemctl status arch32.service" is as follows:

   Loaded: loaded (/etc/systemd/system/arch32.service; disabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since Fri 2015-05-29 18:10:29 EDT; 11s ago

Here's what my arch32.service file looks like:

[Unit]
Description=32-bit chroot

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/usr/local/bin/arch32 start
ExecStop=/usr/local/bin/arch32 stop

[Install]
WantedBy=multi-user.target

Here's what my /usr/local/bin/arch32 file looks like

#!/bin/bash

## User variables.
MOUNTPOINT=/opt/arch32

## Set MANAGEPARTITION to any value if /opt/arch32 resides on a separate
## partition and not mounted by /etc/fstab or some other means.
## If /opt/arch32 is part of your rootfs, leave this empty.
MANAGEPARTITION=

## Leave USEDISTCC empty unless you wish to use distccd from within the chroot.
USEDISTCC=
DISTCC_SUBNET='10.9.8.0/24'

## PIDFILE shouldn't need to ba changed from this default.
PIDFILE=/run/arch32

start_distccd() {
	[[ ! -L "$MOUNTPOINT"/usr/bin/distccd-chroot ]] &&
		ln -s /usr/bin/distccd "$MOUNTPOINT"/usr/bin/distccd-chroot

stop_distccd() {

		mount -t proc none "$MOUNTPOINT/proc"

			done
		fi
		
		rm -f "$PIDFILE"
		;;
	*)
		echo "usage: $0 (start|stop)"
		exit 1
esac

Any ideas as to what's going on?
