I have a simple little function that calculates a price quote based on the options chosen in 4 different drop down  lists (Select elements) and 2 sets of Radio buttons. The total price is written into a div and is updated each time site visitor changes the value of Select or Radio button elements.

I use Change event handler to fire the calculation function. It works perfect in Firefox, Chrome, Safari, but the calculating function doesn't get triggered in IE8.

Here is my web page with this calculator:  http://www.justaddsolutions.com/justaddwebsite/prices/

Is Change event handler not supported by IE8?  If so - can you recommend how to trigger the calculating function on change in Select or Radio button fileds, so that it also works in IE8.
