that is the code I have been working on.

here are the errors
1. warning C4244: '=' : conversion from 'double' to 'float', possible loss of data
2. error C2447: '{' : missing function header (old-style formal list?)
3.: error C2059: syntax error : '}'
4 : error C2143: syntax error : missing ';' before '}'
5 : error C2059: syntax error : '}'
6: error C2447: '{' : missing function header (old-style formal list?)

10: error C3209: ' ' : Unicode identifiers are not yet supported
11: error C3209: '(1' : Unicode identifiers are not yet supported

It is suppose to ask for the price, interest rate, down payment, trade in, and then give them monthly payment for 24 \, 36, 48, 60;mos

I have hit a brick wall any help is appriciated on getting this code worked out. Thanks!!!

There are too many compile errors to be counted.
For example

void getdownPayment(float& downPayment)[B]; // you dont need this semicolon[/B]
{

There are a lot of functions that have similar errors.

Also it looks as if you are not saving the file in ASCII format. Best thing is to copy and paste the code to notepad and overwrite your original source file using notepad save as. That should rid you of the unwanted unicode characters.
Your compiler outputs the line numbers where the compile errors occur. Go to those lines and correct them yourself.
Properly indent the code. I see some mismatched braces and brackets. you can catch those by properly indenting code.

now here are my errors
: warning C4244: '=' : conversion from 'double' to 'float', possible loss of data
: error C2065: 'tradeIn' : undeclared identifier
: fatal error C1903: unable to recover from previous error(s); stopping compilation

Thanks in advance for any help correcting these

To many errors you have. Remove ; after void gettradeIn( float& tradeIn) . Where void getdownPayment(float& downPayment) func ends?

You should read wolfpack's post more carefully:

For example

Code:
void getdownPayment(float& downPayment); // you dont need this semicolon{

There are a lot of functions that have similar errors.

Still in your code:

void gettradeIn( float& tradeIn); //remove semicolon
