AFAIK js is set to enabled by default in IE but you can check to be sure. A little more complicated than FF. Click on internet options from Tools...then in the popup window click the internet icon...click the security tab at the top...go down and click "custom"...a popup will open...scroll down to scripting and find active scripting and choose enable if it isn't already enabled. If you're asked to confirm answer yes. Click okay. You may need to restart IE.
I don't really think js is the problem here but I hope that works for you.
