where do I put the ->?

You have declared grabSolenoid as a pointer to a double solenoid object. The member functions like Set() only work on an actual object. You need to dereference the pointer before you can call the function. The '->' is a small bit of syntax convenience that lets you dereference the pointer and do the equivalent of a '.' at the same time.

Just replace the '.' with '->' between the variable name and the function name.
