Timer doesnt work

This is my little Timer, but it doesn`t work

s = 0
m = 0


function s()
sleep(1)
s =s+1
end

function m()
if s == 60 then
m = m+1
end
end

s()
m()
write("Sec: "..s"Min: "..m)


Sorry i don`t know how to upload the pastebin

The error is:Timer: attempt to perform arithmetic __add on function and number.

Thanks for your help!

You cannot use the same name for your variables and functions. They overwrite each other.

In addition, you never reset the seconds to 0, could cause some problems.

thanks a lot it works now
