TWRP flashing error-please explain

I just unlocked my bootloader but keep getting an error when trying to flash TWRP (see in red below). I have tried both 3.0.2-0 and 3.1.1.0. I got both files from the TWRP website. I have turned the phone off immediately after flashing and tried to reboot into TWRP but that hasn't worked.
Need suggestions please.

I got it. I re-read the "how to" thread and this is what I wasn't doing: Reboot to recovery after flashing the twrp image. Then reboot your device from recovery.

Problems loading LineageOS CM14-1

I have unlocked my Moto-Z play. When I try to use fastboot I always get:

(bootloader) slot-count: not found

I boot the phone, copy twrp.img to /sdcard/twrp.img and then do a 'fastboot boot twrp.img' and when I try to find twrp.img in /sdcard, it isn't there. If I go in with 'adb shell' and do an 'ls' I can see the 'twrp.img' file. but TWRP itself doesn't show it when I select 'Install Image'.

Any suggestions?

What do you mean by TWRP not flashing, do you mean the error that appears or not having TWRP present after flashing?
What happens if you reboot directly to recovery after you flash? That error is normal and usually if you boot normally after flashing TWRP the stock recovery will overwrite the TWRP. By booting to recovery you'll fix TWRP and thus should be able to boot as normal afterwards.
Of course, do not accept OTA updates if you're choosing to stay on stock ROMs with TWRP flashed.

Moto X-PLAY recovery TWRP

I have Moto X-PLAY running OTA stock Android 7.1.1 (SKU:XT1562) I have successfully unlocked the bootloader, but I'm having a problems installing recovery TWRP (twrp-lux-3.1.1-r1.img) following a youtube video using a Moto X PLAY.
Using the command: fastboot flash recovery twrp-lux-3.1.1-r1.img
I get this back:

reboot phone into ‘Recovery Mode’ and get the error:
No command (with an Android on it’s back’!’)
I have had looked for newer img file on TeamWin site. But does not list my device in it’s list.
I would like to know what is going wrong and how would I fix this problem.
Thanks for any help.

Maybe installing a new firmware fix it but if you install 7.1.1 by OTA you need to install again 7.1.1 but by firmware..

Ok problem solved after flashing TWRP over stock recovery, it will be overwritten by stock on reboot. You have to reboot into the bootloader using command: fastboot reboot-bootloader
then choose Recovery, and than after it boots, You can safely reboot to system as it won't be overwritten anymore.

Good to know that you solved it

Can you explain it a bit clearly. I am confused. But i am facing the same issue which you mentioned in your question..

He did explain clearly (including the command you need after installing TWRP). Just follow the steps.
After installing TWRP don't boot into system, boot into boot-loader first! Otherwise TWRP will be overwritten by stock recovery.

Moto G6 plus has the recovery partition merged with the boot one. If you want to use TWRP, you have to use the boot command instead, and then flash a TWRP zip installer for this phone.

Thanks for the reply.
I am a noob when it comes to this.
How do I use the "boot" command?

Type "fastboot boot the-name-of-the-twrp-file.img".
Also as advice and nothing related, if you want to revert your changes back to stock, don't forget to NEVER RELOCK your bootloader. There's a low chance of getting your phone back fully functional after this mistake.
