[Pause between tween in timeline]

Hello,

 

I need a short pause between to tweens in my timeline. I've added a "+=0.75" like explained in the docs, but this doesnt work. Any hint for me.

 

Best

P.

tl.add( TweenLite.to("typo1", 1, {opacity:1}), 0.5 );
    tl.add( TweenLite.to("typo1", 2, {opacity:0}) );
    tl.add([TweenLite.to("top", 0.5, {opacity:1}), TweenLite.to("bottom", 0.5, {opacity:1})]);
    tl.add([TweenLite.to("mask", 1, {left:1000}), TweenLite.to("bg", 1, {opacity:0})] );
    tl.add([TweenLite.to("top", 1, {top:-100}), TweenLite.to("bottom", 1, {bottom:-60}), TweenLite.to("eyes", 1, {opacity:1})]);
    tl.add( TweenLite.to("logo-small-grey", 2, {opacity:1}), 6 );
    tl.add([TweenLite.to("eyes", 1, {opacity:0}),TweenLite.to("typo2", 1, {opacity:1})]);
    tl.add( TweenLite.to("product", 1, {opacity:1}));
    tl.add( TweenLite.to("stoerer", 1, {left:560},"+=2"));
    tl.add( TweenLite.to("stoerer", 2, {opacity:0}, "+=2.5"));
    tl.add( TweenLite.to("product", 1, {opacity:0}));
    tl.add( TweenLite.to("typo2", 1, {opacity:0}));
    tl.add( TweenLite.to("date", 1, {opacity:1}));
