Accordion with Motion Path

After watching the recorded webinar on creating accordions with animation, I created this one. It has three tabs that each slide out when selected to display the information. I was able to get this to work yesterday (and even figured out the timing for when the content should fade in on the open accordion window). However, now I cannot get it to work right. I can make my way through each tab once (in any order). However, I cannot revisit a tab successfully. Sometimes the tab will slide but the content will not appear. Sometimes the tab won't even slide. I have tinkered with this so much (and deconstructed some of the examples posted) that I can't even see straight. Can someone take a look to tell me what I am missing? Thanks!
