calculations add to price
That was good in theory, but I already have prices on the items, when I added the charges like you suggested, it added the charges to the total and gives an incorrect subtotal/total cost. I could remove the prices, but then I get a incorrect subtotal with a correct total.
There's a misunderstanding here: I not only need to collect for the cost of the cake (which has two options, $20 for 1/4 sheet and $40 for 1/2 sheet) but then I need to charge a $50 deposit for the overall reservation. So, overall I need to get a payment of $70 or $90.
I have an existing ecart with multiple items for parties (and cakes). A party may cost $10 per person (with a minimum of 10), in addition they may (or may not) order a cake. Everything currently works fine, calculating the total cost of the parties. However there is no online payment system. Everything is paid via phone or check. They would now like to collect deposits and the cost of cakes when reserving the dates and remainder at the party.
I'm probably not explaining this very well (sorry). Is there a way I can send you the url privately?
