You can not declare variables with spaces in their name.

Do not use

Code: [Select]

double down payment;
Use

Code: [Select]

double down_payment;for example.

Btw. 'down payment price' is not declared at all and scanf needs the address of the double, not its value!

It really helps if you get used to using code tags when posting code (snippets) in the forum (that's the # button/icon just above the message entry box)...
