Call function from external method in same class

For some reason I cant figure this out,

I have a function thats in a method in a class…

I have a second method in the same class, trying to call the function from the second method

eg:


package com.sarin
{
	import flash.display.*;
	import flash.events.*;
	
	public class TestingClass extends MovieClip
	{
		public function TestingClass() 
		{	
			function insideFunction()
			{
				myMC.gotoAndPlay(15);
			}
			
		}
		public function methodTwo()
		{
			trace("test");
			insideFunction();
		}
		
	}
	
}

trying to get insideFunction() called from methodTwo()

Hope that makes sense

thanks
