Greta - as you have indicated there is currently no way in the Products|Information screen to see the totals (remember that there will be a max and a min total given that each item has a low and high quantity). There is also the problem of which fixed price to use when one or more of the items has multiple fixed prices. There is the question of which pricing and service ratio to use - presumably that for the current practice location.  Finally there is the problem of patient weight dependencies - ie the template can contain items that are present/absent depending on the patient weight.

All the above indicates that one cannot simply add a 'total price' field to the Product Template.

A possible approach would be to add an Estimate button to the Product Template view/edit screen - pressing this would bring up a display of the min and max totals using the default (or first found) fixed prices, the current practice location and patient.

It seems to me that this a project sized task.

Tim A may have other suggestons as to how to proceed.
