I am not sure why i am getting this error please help

Given the parameters set in the template below, create a script that uses Euler's method to chart the height of water in the tank (y in the diagram below) of Pliney's fountain. Use a time-step of 0.01 seconds and investigate from t=0 to t= 100 seconds. Assume the tank is initially empty.
