remove the "local" from your global function and it works... so use

 01 -- A function that accepts one value and returns one value 
02 function mntestfunction(testvalue) 
03  -- Put function script here 
04 mnvalue = testvalue;  -- Access testvalue 
05  -- if statment test 
06 if (mnvalue==1) then 
07  -- Do something here 
08 result_value= "OK"; 
09 elseif (mnvalue==2) then 
10  -- Do something else here 
11 result_value= "Very Good"; 
12 elseif (mnvalue~=1 or mnvalue~=2 ) then 
13  -- Do something else here 
14 result_value= "Not Good"; 
15 end -- end if statment 
16  --------- 
17 return result_value;  -- Return result_value 
18 end 
19

instead of

01 -- A function that accepts one value and returns one value
02 function mntestfunction(testvalue) 
03 	-- Put function script here
04 	local mnvalue = testvalue;  -- Access testvalue
05 	-- if statment test
06 	if (mnvalue==1) then 
07 	 	-- Do something here
08 		local result_value= "OK"; 
09 	elseif (mnvalue==2) then 
10 	 	-- Do something else here
11 		local result_value= "Very Good"; 
12 	elseif (mnvalue~=1 or mnvalue~=2 ) then 
13 	 	-- Do something else here
14 		local result_value= "Not Good";	 
15 	en d-- end if statment
16 	---------
17 	return result_value;  -- Return result_value
18 end

You could also do this:

-- A function that accepts one value and returns one value
function mntestfunction(testvalue)
	-- Put function script here
	local mnvalue = testvalue; -- Access testvalue
	-- if statment test
	
        if mnvalue==1 then
		-- Do something here
		 result_value="OK";
	elseif mnvalue==2 then
		-- Do something else here
		 result_value="Very Good";
	elseif mnvalue ~= 1 or 2 then
		-- Do something else here
		 result_value="Not Good";	
	end-- end if statment
	---------
	return result_value;  -- Return result_value
end

The difference is I removed the () around the declaration of variables like
(mnvalue = 1) becomes mnvalue = 1

you dont need the () also the mnvalue ~= 1 or 2. you can easaly compare the same variable to more then one value, you dont need to test the variable twice.

Thise are just design notes, they have no effect on the executet script but as saied above all you have to do is remove the local from the variable name.
