You have two #define statements at the top of your code

#define trigPin 3; 
#define echoPin 2;

The way #define#define works is that it replaces every instance of the name with everything after it on the line so trigPintrigPin is being replaced with 3;3; as opposed to 33 as intended.

Fixing this should solve some of your problems.
