problems with links?

This is the only code I have and I get no errors but when I click on a certain button it wont go to that certain SWF file?

import fl.transitions.*;
import fl.transitions.easing.*;

//Make the buttons look like buttons
Home.buttonMode = true;
Big_Square_Baling.buttonMode = true;

//don't get garbage collected

loader.load (urlRequest);
}

//If we clicked the second button, we load the Big Square Baling page
else if (e.target == Big_Square_Baling) {

loader.load (urlRequest);
}

//is not clicked
else if (e.target == Wrapping) {

urlRequest = new URLRequest("Wrapping.swf");
loader.load (urlRequest);
}

//We load the Chopping page since we know that the home page, the Big Square Baling page, or the
