How can I add the values in a table column with CSS3 and jQuery?
Here's a link to my test page: http://www.co.frederick.va.us/dev/jquery_math.html. It's simpler than where this code will ultimately go.
I want to add the values in the second column. I found this little tutorial, but I ran into some problems: http://naspinski.net/post/Use-jQuery-to-add-all-the-values-in-a-table-column_.aspx.
It doesn't work. Firefox debug console tells me "Unknown pseudo-class or pseudo-element 'gt'." What's up?
I'll go ahead and attach my code, but it may change on the page as I tinker with this.
