Ajax not working in IE7, works in IE8 and firefox

I added an Ajax script to my website.

When viewed in IE8 or Firefox, clicking the Thumbs up or Thumbs Down icons will result in the user casting a vote instantly via ajax.  This works correctly.

When I do this in IE7, the vote gets cast but only after the page refreshing.
I also notice a Javascript Error in IE7 but I can't pinpoint exactly what it is.
I'm not sure if the issue is related.

I've also read this article on Experts Exchange, but I'm unsure of which variables I would change in my code:

Any ideas?

hmmm...that might be important? How do you know an error has occurred? Can you tell us anything about the error?

Then please, show us the 715th character of line 2.

I can't.  Line 2 is session_start().  And there isn't 715 characters.
I don't know how to troubleshoot this. That's why I'm posting here.  This message doesn't make sense to me.

Again, the function works but refreshes the page instead of letting Ajax doing the update.
Only an issue in IE7.

What is line 2 from the first JavaScript file in your page?

In the file init.min.js.php
near the code
spinner_large_red.gif" />',};switch(template)

Open in new window

You have a comma followed by a brace:

Open in new window

Try getting rid of the comma.  If that doesn't fix it, then you'll probably have to un-minify your code to see what's really going on.

Perfect!  This fixed both the Javascript issue and the Ajax issue.

I can't believe it was ONE COMMA!

Many thanks!

When I was in college, my teacher told me that a person was almost killed by a medical device because of a misplaced semicolon.  

Anyway, glad to hear it's working.
