C++ Code Error

On line 69 I receive an error saying that total is not declared in this scope, I am unsure what I did wrong.

[Iwakao]

in "discountCost = mCost(rCost, nights, total, memberDiscount);" total was not declared.
After that I got that your "char getMembership()" is not named properly at the end of the code, it just say "char membership()"

1) Please use code tags when posting code, to make it readable:

2) In your main() function, you're attempting to use a variable called total, in your call to mCost(). But you haven't declared that variable anywhere in main().
