Please care for posting the compelete error message instead of mentioning only, that there is one.

How do you start this function? Using the green triangle? Then you do not provide any input and n is undefined. A function defined by

function read(n)

must be called e.g. as "read(5)"

The next problem will occur then: what is "write()"?
