Do you see where you made a mistake?

In the other topic of yours Graham wrote:

Then on the end of every g-code file just before the M30 enter

#1200 = #1200 +1

But a g-code error pops up

This one does not throw error

When you have math operations, they have to be enclosed in square brackets. Notice the percent (%) sign at the end of the program. If your program does not have CRLF after M30, this is the way to be on the safe side, % is anyway ignored.

Thank you very much but I still don't count the number of completed items

Thank you very much but I still don't count the number of completed items

Not incrementing DRO, user variable incrementing.
But, you can write a macro and add it to your macro folder and it works perfectly:

count = getuserdro(1200)
count = count + 1
detuserdro(1200, count)
Save it as M900.m1s

then add it to your GCode program:

M900
M30
%
It increments DRO 1200 every time before rewinding program.

Thank you very much for help .
And how do I add a macro?

Is that how I was supposed to do it?
Because it still doesn't work

Ok, typing error
last line in macro should be setuserdro...

I realy don't like when people do blind copy/paste.

Hello
Thank you very much, everything works beautifully, I am very grateful. Again thank you very much 

Tomorrow I will insert a screenshot of how it all looks
