Have completed an update to this contribution. Was originally ported to 'Max by JohnW and is now updated to a later release, specifically for 'Max 2.5.1
At present it is not multi-lingual but it would be fairly trivial to add the required changes. No inherent bug fixes have been tackled (I noticed small layout issues) but the English text has been 'cleaned up' a bit.
I was asked by a client to integrate this contribution to 'Max and hence its incomplete nature - it was a relatively quick & dirty conversion and I need to get on with other things. I reckon that it could prove to be useful to some but I suggest you check the relevant ocsommerce forum, for any issues in using it.
As it is incomplete, with regards to language functionality, I haven't added it as a Project but it can be downloaded from the osCmax section of my main website.
