[Solved] trouble getting the right settings for a static IP

Question

I'm not sure of how to best set my static IP connection in Arch.
In Manjaro/Ubuntu/etc. I use the Network Connections App and put in my IP, Subnet mask, Gateway and DNS. When I've tried to do it in the commandline to set up Arch, I get a "cannot make connection" error (or something of that sort) when I put in the gateway.
Relevant info for my connection (with XXX and YY standing in for numbers) - this is what I enter for Manjaro/Ubuntu (and what I attempted to use in the commandline to setup Arch - though I added the subnet mask /24 for the IP):
IP: XXX.YY.37.220
Mask: 255.255.255.0
Gateway: XXX.YY.31.1
The output of "ip route show" in a correctly configured/connecting instance of Manjaro on my system is:
default via XXX.YY.31.1 dev eno1 proto static
XXX.YY.31.1 dev eno1 proto static scope link
XXX.YY.37.0/24 dev eno1 proto kernel scope link src XXX.YY.37.220 metric 1
From the beginner's guide, it seems I should set up netctl?  I'm wondering what the right settings would be for this based on the above?

FOllowing the Arch wiki's section on "Persistent configuration on boot using systemd":
I created config file:
/etc/conf.d/net-conf-eno1
address=XXX.YY.37.220
netmask=24
broadcast=XXX.YY.37.255
gateway=XXX.YY.37.1
and created /usr/local/bin/net-up.sh
#!/bin/bash
ip link set dev "$1" up
ip addr add ${address}/${netmask} broadcast ${broadcast} dev "$1"
[[ -z ${gateway} ]] || {
ip route add default via ${gateway}
and /usr/local/bin/net-down.sh
#!/bin/bash
ip addr flush dev "$1"
ip route flush dev "$1"
ip link set dev "$1" down
and /etc/systemd/system/[email protected]
[Unit]
Description=Network connectivity (%i)
Wants=network.target

ExecStart=/usr/local/bin/net-up.sh %i

[Install]
WantedBy=multi-user.target
when i try to execute systemctl enable network@eno1 it reports:
Error: an inet prefix is expected rather than "/".
I have narrowed this error down to the net-up.sh, as when I execute sudo ./net-up.sh eno1 it reports the same error as above.
