why do i get this sort of error

The function called pitch() returns more than the 2 outputs that you are requesting. It takes 3 or more. What does the function line of pitch (in its source code if you have it) look like? Or, if you don't have source code for that function, then what does the documentation say for how to call pitch()?

The Audio Toolbox pitch function (that matches the syntax you quote) produces two outputs, and (other than a missing right parenthesis), the assignment appears to be correct.

Check to be certain that you have not defined your own ‘pitch’ function that is overshadowing the Toolbox function.

Run:

which pitch -all

from a script or your Command Window and report the resuts. (I suspect that more than one of them will be found.)
