Error messages when trying to run GCode

There is home=0  home_search_vel=2  home_latch_vel=-0.625 .Somehow  i think, if home is 0, home_search_vel should be minus direction and home_latch_vel  plus direction, and scale inverted instead.

With this setup, after homing , do  mdi G0 G53 X1 Y1, does it go in the right direction?

you will have to excuse a complete beginner here, does this mean i change the home_search_vel to -2 and the home_latch_vel to 0.625. When you say scale are you refering to the INI file scale that is 800 at present, do i invert by adding a minus, i have never had to do that.
Also it was pointed out that there is no home_final_velocity, im guessing i have to add this in which case where do i insert the text

Hi i have done the sequence as in images but still no "home all" button lol, every thing i try brings up an error message and i know the axis are homed but screen error messages insist they are not, think i have a ghost 

Hi have added the missing text and also sequenced the axis for homing, dont know if its correct though or whether i have to add anything else either in here or the HAL so could you have a quick look for me. the machine is still sending error messages and still no home all button
Many thanks for your help

Ok everyone thank you so much for your help, we now have a home all button and no error messages. I added the code that was suggested for final_vel. The main problem was that the homing needed sequencing which i have done but ommited the A Axis, filled this out on the INI file and hay what do you know. Now we need to work out how to change the speed because when we ran it in air it took off at 90 miles per hour
Thank you all
