You have probably used sum as a variable in your code. Check it by typing
sum

You probably redefined sum to be a variable or function in your code, thus destroying it, or actually just using yours in preference to the built-in sum() function. Try putting these lines in and seeing what it says.
whos sum
which -all sum
