One-Page Checkout [Support Thread]

[lat9]

No good dead goes unpunished. I can click the button....and now I'm getting the famous "You must choose a shipping method for your order before the order can be confirmed."

In the console, I do see:
jquery.checkout_one.min.js:5 Uncaught TypeError: Cannot read property 'top' of undefined
at o (jquery.checkout_one.min.js:5)
at t (jquery.checkout_one.min.js:5)
at HTMLSpanElement.<anonymous> (jquery.checkout_one.min.js:5)
at HTMLSpanElement.dispatch (jquery.min.js:3)
at HTMLSpanElement.r.handle (jquery.min.js:3)

I don't think I mentioned this, but I'm using OPC 1.5.0

Please update the setting on the site to use the unminified version of the jScript files (that'll give a bit more information as to the location of the issue).

How is the associated product defined (I see it's free shipping)?
