user4509: As the title suggests, I have many "expected `)' before ';' token" errors. The issue is, I have this stuff in. So now I am confused, why am I getting this if the things are there.
I am new here and had an issue with adding code, so here is the pastebin link to it: http://pastebin.com/4WXxsXkB
And here is the the pastebin link to the error:
http://pastebin.com/QyehP86M
Does anyone understand how this could happen?

user3818: You have two #define statements at the top of your code 
#define trigPin 3; 
#define echoPin 2;

The way #define works is that it replaces every instance of the name with everything after it on the line so trigPin is being replaced with 3; as opposed to 3 as intended.
Fixing this should solve some of your problems.
