Im so sorry, I forget to post the pic

 

[wade_hassler]

It may be because you did not give the compiler a prototype of "ReadTemperature()", forcing it to use an assumed type.
There are prototypes for almost everything else, so give that a try.

tks so much but I see the algorith is true, :-( I can't do anything

The remark gave by wade_hassler makes all sense.
You are using a function on line #144 that was implemented after, on line #159.

As mentioned before, you can try inserting the code bellow at line #2 of your code above.

void ReadTemperature(void) ;
