if you don't use the var keyword, the variable is automatically  
declared as global (in the JavaScript meaning, not the Global  
object). And it's usually very hard to figure out the problem (for  
example, if you have 2 jsui running at the same time, they will share  
the i variable, which is really not what we want in such situation).

Have a look to the anythinng() method. The message name property  
should have the symbol "3:1". Although I didn't test, the following  
should work:

var Ratio = ["1:1", "2:1", "3:1","4:1", "6:1", "10:1"];

function anything()
{
	var i; // this is really important ;-)

	for(i = 0; i < Ratio.length;  i++) {
		if(Ratio[i] == messagename)
			outlet(0, i);
	}
}
