Check all quotation marks in “/etc/X11/xorg.conf.d/99-calibration.conf”. I suggest to substitute them by manually retyping them. I guess copying the text from the forum changed the quotation marks in some way.

yes you were correct the quotation marks were replaced with these > >.
manually retyped and the UI is back up and running!
Bad news the damn calibration didn’t work, it’s still the same.

rechecked and its gone in fine?
tried this to, the UI works just the calibration is all off, still does the same thing.
Wish it was just a little easier to do but these things never are i guess. At least i am learning a great deal!
I suggest to run “xinput_calibration” again. IMHO the current values look weird.

If these values are estimated wrong, either supply it manually with the --precalib option, or run the ‘get_precalib.sh’ script to automatically get it (through HAL).

Hm, those values don’t look that different…
Maybe it could be an option to use a calibration file from the manufacturer of the display. This wouldn’t be ultra precise, but probably better than what you have now, Could you provide the name of the manufacturer and the exacr model name of the display?
got it from ali express!
also my cursor moves backwards still. So up and down is left and right, right and left is up and down!
Not too much of information available over there… 
So that is your main problem and the cause why you want to calibrate, I guess?
Maybe put on hold using xinput_calibrator and using “/etc/X11/xorg.conf.d/99-calibration.conf” for the moment and lets have a closer look if and how the touch is inverted or swapped.
For now I suggest to “deactivate” “99-calibration.conf” by renamig it
sudo mv /etc/X11/xorg.conf.d/99-calibration.conf /etc/X11/xorg.conf.d/99-calibration.conf.bak
After rebooting systematically test where the cursor appears when you touch the screen in the corner areas and how it moves when you swipe from left to right and from up to down. Describe the results in detail so I can follow it.
Also please show the contents of “/boot/config,txt” and “/boot/userconfig,txt”:
cat /boot/config.txt
cat /boot/userconfig.txt

ill get this done over the weekend and report back gvolt, thanks for your patience and help!
Hi gvolt
so i renamed the file to deactivate it, after doing this i rebooted.
When i touch the left hand corner of the screen the pointer appears on the right hand corner about an inch away.
when i touch the bottom right hand corner the pointer appears on the top left hard corner.
when i touch the bottom right hand corner the pointer appears on the bottom left hand corner]
when i touch the top right hand corner the pointer appears on the bottom right hand corner.
sliding my finger left moves the pointer up, sliding it right moves it down.
Sliding my finger up move its right, sliding my finger down moves it left.

This appears contradictory. Could you check again and / or clarify please?
From your description of the sliding / moving directions the X and Y axes seem to be swapped.
Now please rename “/etc/X11/xorg.conf.d/99-calibration.conf.bak`” back to “/etc/X11/xorg.conf.d/99-calibration.conf” and describe again where the cursor appears on touching at the four corners also swiping in the four directions.
my apologies
touching the top left hand corner brings the pointer to the top right hand corner
touching the bottom left hand corner brings the pointer to the top left hand corner
touching the top right hand corner brings the pointer to the bottom right hand corner
touching the bottom right hand corner brings the pointer to the bottom left hand corner.
