index must be a positive integer or logical

For the following operation in my code:

    result = max((1)-(abs(sum_A-sum_B)/sum_A-sum_C),0);

I got the following error:

Attempted to access max(356.87,0); index must be a positive integer or
logical.

Although I'm intending to simply retrieve the maximum value here, provided that when I run the line as stand-alone, I get the max retrieved correctly.

What could be the issue?

Thanks.

Are you using max as a variable somewhere in your code? If not, it's probably in your workspace, so do a

 clear max

and re-run your code. At any rate, try to avoid variable names that are also function names or reserved words.
