In English, that means you can't make use of variables like [price], [taxable], [textA], [quantity], etc. You only have access to order file header variables like [email], [header1], [shipVia], etc. You *do* have access to [sku], because that's one of the variables you pass explicitly into the $Add command.If you want access to line item variables, you can pass them as extra values in the $Add URL, or you can do [lookup] in the body of the formula.I know this is a pain, so I'm going to try to figure out a nicer way to handle it in the future. My problem right now is that when you're $Add-ing to the cart, the lineitem you're *about* to add doesn't exist yet, so I can't give you those variables because there's no context for them yet. Maybe I'll 'fake up' a context in the future that holds all the lineitem information so it's easier to put into formulas.And remember, formulas were invented as a security measure: it would be very easy to just put the price right into the $Add URL when you're adding to the cart, but then it would be too easy for hackers to simply change the price to anything they want. So formulas were invented as a hack-proof way to change prices without outsiders being able to mess with them.Grant Hulbert, V.P.
