You didn't use any indentation. That's a huge mistake.

first of all: using file:close() in the say function leads to the script not being able to write anything to the file after you've written something for the first time

Also have problem on line 6

local msj = string.sub(8,50)

it should be

local msj = string.sub(txt,8)

Why don't you tab your script?

LUA ERROR: sys/lua/report.lua:11: attempt to index local 'file' (a nil value)

Line 11:

file:write('\nReport @ ['..os.date('%X %x')..']:"'..txt..'"')

reportfile="sys/lua/report.txt"

addhook("say","report")
function report(id,txt)
	if (string.sub(txt,1,6) == "!report") then
		local file=io.open(reportfile,"w")
		file:write("\n"..player(id,"name").."("..player(id,"usgn")..") reported "..string.sub(txt,8))
		file:close()
		msg2(id,"Okey, i will take care of it....")
	return 1
	end
end

"a+" append update mode, previous data is preserved, writing is only allowed at the end of file.
There must be a file for update it.

That would not work. You're using write mode.

a+ is append mode +, which adds lines to the end of the file. What you did was erase all reports and create a new one, because you used w, edit mode.

The savefiles are .rep - this is just because it looks great. You can open them with notepad, because .rep is not an actual file type.

Make the folder 'reports' in sys/lua
