Hey all,
I'm hitting a very frustrating wall trying to make my tweens work in IE8. When attempting to transform my elements with the x and y properties, I get "error: Invalid argument" on line 1308, which I've traced back to line 1236. It seems that at the beginning of _setIETransformRatio, the _gsTransform object already has the value 'NaN' for its x (or y) property. Strangely, the properties show the correct values right up until the tweens begin, but as soon as they do, the values become NaN.
I've searched the forums to no avail. I don't think it's my CSS, as the problem still shows up if I disable it all. Also worth noting is that my timeline is actually paused and controlled by the user's scroll position.
Working on putting together a codepen, but any help in the meantime would be greatly appreciated!
