Hi,

Some suggestions welcome…

1) I need to pass a calculated field value Total = (Quantity * Price) to the "$ Single Product" default field and add the "readonly" attribute in the Additional Attributes section. I can do it for a regular text box but not for the "$ Single Product" type.

Is there a simple way to do this ?

(As far as I can tell it doesn't look like the "$ Single Product" field can be used within the basic Calculations tab for mathematical operations - it doesn't show in the list of available fields when added to a form. Maybe an issue with its more complex field parameters ?)

2) Subsequently, I'd like to propagate the value of the "$ Single Product" field to an additional form and move to payment options. I succeeded in doing this with the described url redirect method for various form field values. But is there a similar way to export these parameters to other shopping cart apps, e.g. J2Store, which can generate shopping cart items with a fixed price from Joomla articles directly ?

Thanks.

I found a workaround by adapting the script from the RS Joomla FAQ: How to add a quantity functionality to a PayPal form.

Other solutions and comments welcome ...

Thanks.
