When you say it turns to 50, where exactly do you mean? Remember you have to tell WebCatalog that the quantity is 50, or else it won't know.I suggest you set up a [SetLineItem] context in your ShoppingCart.tmpl file that tweaks the value of the quantity at the time someone is $Add-ing to the cart.[ShowIf QUANTITYNEEDSCHANGING] [SetLineItem cart=[cart]&index=[NumLineItems]&db=catalog.txt]quantity=NEWQUANTITYVALUE[/SetLineItem] [/ShowIf]And then change your [LineItems] loop to incorporate the newly-changed order file:[OrderFile ShoppingCarts/[cart]] [LineItems] ...your usual line item stuff here [/LineItems] [/OrderFile]Now every time you add something to the cart, its quantity gets changed if necessary just before being displayed.The reason you have to wrap that extra [OrderFile] context around the [LineItems] is a bit technical: if you don't do it then the LineItems would still be in the context of the *old* order file before it had been modified. So by explicitly creating a new OrderFile context, it has a chance to get the new values so the LineItems will show the correct quantity.Sorry for the complexity, but HTML forces us to do things like this because the information you need is always 'lagging' one step behind: the values are stored in the visitor's web browser, and haven't had a chance to get to WebCatalog until after the visitor clicks something. Otherwise it would be a simple matter to just change the quantity in the $Add hyperlink on the previous page, but that's too early in the process.Grant Hulbert, V.P.
