You must start on the top and work your way around all the errors.
EDIT: I started looking in Tool.h and half the stuff was missing or wrong, you have to start with something alot easier.

	{ partNumber = i; toolName = s; inStock = i2; unitPrice = d; }

	Tool() { partNumber = 0; toolName = ""; inStock = 0; unitPrice = 0; } // You need a default constructor
public:
