The tutorial may well be one of a series but I've not been following anything prior to it because I'd asked how to add incremental pricing and that was the article I was directed to.
I'm struggling to comprehend your suggestion that having a product recordset filtered on a form post is in any way "unusual".
It certainly isn't unusual and it would be nice, rather than eCart just dying and no longer working, if it could cope with basic stuff like this instead of, after the expense we've had upgrading, finding ourselves back to hand-coding everything. It's a disappointment Jason.
Will I have to hand code this every time I want to have an "Add to Cart" button on a page where the recordset is filtered on a form post?
Can eCart only deal with recordsets that are filtered by querystring?
