Not sure how to set up Task 2 of 5 on querying relational databases, not sure if multi table join is correct?

I got something back trying this, I know its wrong can't figure out why

SELECT MakeName, ModelName, VIN, StickerPrice FROM make INNER JOIN Model ON make.MakeID = Model.MakeID INNER JOIN Car ON make.MakeID = Car.ModelID;

okey 1st witch chalange ? any link to it ?

i try fix it without it

1st :

if you USE JOIN you should specify with TABLE you selecting info why? because there can be multiple same name coloms in 1st and 2nd table for example

your : 

MakeName, ModelName, VIN, StickerPrice

Fixed (just example because idk question info): 

make.MakeName, Model.ModelName, Mode.VIN, Car.StickerPrice

2nd: Are you sure you dont need to use "AS" ?

3rd : are you sure with this ?, because MakeID and ModelID is diffrent and i dont think they chaosed diffrend collum names : 

make.MakeID = Car.ModelID;
