I'm having a problem with a TweenMax in ie8. i'm not sure if it's a "color" tween error or not though. The error message is:

Invalid property value.
Line: 16
Char: 838

The website is: http://www.paragoncasinoresort.com/


I'm kind of stumped here as to what that could be. It's working on all other browsers including IE9+. Any help would be greatly appreciated.

hmm, I'm also seeing errors related to a pickdate.js


Maybe get rid of that one first and then see if the TweenMax one goes away?


its really difficult to trouble shoot one tiny error in a full blown production site, especially in IE8. I'm not even sure where your scripts are that are using GSAP. 

The best thing to do is try to isolate the tweens that you may think are causing the trouble and start building a reduced test case in CodePen.

The CodePen editor doesn't work in IE8 but all demos will in "full" view like this one: http://codepen.io/GreenSock/full/qeHac/


I tested that one in IE8 and didn't get any errors. This simply verifies that code in TweenMax probably isn't the problem. 

The problem most likely has to do with you asking TweenMax to read values that it can't get to. This may be something wrong with your code, or something we have to tweak for IE8. No way to tell though until we have a better shot at looking at an isolated demo.

Bonjour Boby - Parlez-vous anglais?

Je ne parle pas très bien le français.

Pouvez-vous créer une nouvelle discussion sur le forum avec une démo sur CodePen et posez votre question en utilisant Google Translate?
