If the Price Guide does not seem to work (figures should change as you click the round buttons), it may be that the code has been blocked from running. Look at the bar just above the window to see if it says:
To help protect your security, Internet Explorer has restricted this file from showing active content that could access your computer. Click here for options...
If you do see this, then click the bar and click Allow blocked content. It should work after that; please contact us if it does not. Please be assured that our code will not damage your computer in any way and nothing is saved on your disk.
