Hi folks, I’ve got my site working in FF, Safari, and IE8, but I need some help getting it to work in IE7. I’m using the Prototype library, by the way. I suspect it has nothing to do with Prototype and more to do with how IE7 and 6 execute JS unpredictably. ![](http://forum.kirupa.com/uploads/kirupa/5772/52c6d7fcc4493394.png) To see the error, click the button. It will only happen about 25% of page loads, so reload the page if you don’t see it. ```php ```
