You must have a variable in your workspace called sum, which is a bad idea.
Make sure that your program or script does not create a variable called sum.
If you enter,
>>which sum
You'll see
sum is a variable.
Enter
clearvars sum
Then try to use sum() again. You should avoid creating variables that have the same name as functions you want to use.
