I tried to post this last night, but it seems to have failed. Apologies if this ends up a duplicate post.
I have an iframe containing an XML/XSL generated list of products. The XSL adds the quantity fields and buy buttons for each item. In the parent document I have buttons to managecart and checkout.
Mangecart seems to work OK but checkout shows $NaN.aN for tax and total.
I've installed a completely un-touched nopcart.js from the original zip file but still get the same result. I've pored over my atpmanagecart.html and atpcheckout.html but can't see where they could affect the result. Also tried altering the tax rate in nopcart.js but to no avail. Makes no difference if I set it to "arizona" rate, Other state or remove selectable tax altogether.http://home.exetel.com.au/peterbmack/atpparts.html
The js and XSL files are in peterbmack/site/
If anyone can help shed light on what I'm doing wrong I'd really appreciate it.
