The error is here

//LEVEL 7
void level3() {

This should be

//LEVEL 7
void level7() {

looking at your code I suggest that you teach yourself how to do arrays - not only would it would reduce the amount of code to perform that same task but it would be an enormouse benefit to you when creating similar applications.

AHA! Thank you so much.

Re: Can't see the problem

I think it might be because you have a boolean var with the same name as the function.

Try instead of
void level6() {

better

void makelevel6() {

for all functions (level3, level0 etc.)

Hint:
Instead of having a boolean for each level have one var:
int currentLevel = 0;
and let it have the values 0 to 13.

You probably need still the functions.

Hint:
instead of

else if (level3 == true) {

you can use

else if (level3) {

...and arrays for the cars of course...

Ok, using arrays with classes has me stumped. Any tips or suggestions? :$

Thanks for the tips. Coding really isn't my strongpoint. Arrays are VERY new to me but I'll definitely look into implementing them. Thanks again.
