Fixed. Had to enclose in a function and then move the var tl out of the click function.
j(function(){
var tl = new TimelineLite();
j('.slide a').click(function() {
var tri1 = document.getElementById("tri-one");
var tri2 = document.getElementById("tri-two");
var tri3 = document.getElementById("tri-three");
var tri4 = document.getElementById("tri-four");
var tri5 = document.getElementById("tri-five");
tl.add (TweenMax.to (tri1, .25, {opacity: 1}));
tl.add (TweenMax.to (tri2, .25, {opacity: 1}));
tl.add (TweenMax.to (tri3, .25, {opacity: 1}));
tl.add (TweenMax.to (tri4, .25, {opacity: 1}));
tl.add (TweenMax.to (tri5, .25, {opacity: 1}));
});
j('.info a').click(function() {
tl.restart();
});
});
