Thanks for the replies guys, I was kinda afraid that would be the case, but nevermind.
I had a look at floyds HTA multiple input form (http://pgmacros.com/community/index.php?showtopic=248) and modified it to suit my needs using textarea tags for the fields i required. Worked out quite nicely although it will take a bit more work to configure it for other product layouts, but the input form should be easy enough for my users
Attached the working version if anyone is interested.
