else statement must immediately follow if's closing braket "}". From your code I cannot tell if else from line 70 is paired with if from line 62, or maybe the one from line 52? Close all the brakets properly. The same goes for while in line 65 - shouldn't it be paired with some do?

In lines 88 and 92 you have another mismatched elses.
