Please use code tags properly and tell us what error you are getting. Just saying "there is a problem" and pasting code doesn't give anyone any kind of idea about what your problem is.

 

Post code tags and I'll give it a shot.

 

if I had to guess without digging into the code and with no indication what the "problem" is, i would say its because you are calling for this function in the Update loop:

but the actual function is named:

 

sorry I am new to unity and I did not know what to do. Thanks for your help.

 

Thanks a bunch. but I did the:

function CarPhysicsUpdate()

but when I hit jun it gave me this:

Assets/535345.js(78,18): BCE0044: expecting (, found 'CarPhysicsUpdate'.

I did research to try to find what that meant and found nothing. Could someone help me.

 

Thats not the only error :LOL: there is a ton of grammatic errors such as : Input - Imput, Rigidbody - Rididbody and so on, dont know where did he get this script but it just amaze me
Script is ok but it needs some grammar check.

 

please edit your first post and put your code inside code tags ( see here for further instructions http://forum.unity3d.com/threads/143875-Using-code-tags-properly ) and also please reformat after doing so. unless you dont do that it is unlikely that someone will help you.

Also without reading your code this error message is genarally caused by syntax error eg. missing ; or foretting a ( or { etc
