Applying charges - only for products in a particular category?

Originally Said By: Ray Borduin

  The RealPrice was added so you could display it if you wanted to.  

So that has nothing to do with the 5% surcharge then, I assume?

  You could still display the Price (orignial price), Surcharge (additional charge) and RealPrice (added together) independently or save them independently in the database.  

How? I don't have Surcharge or RealPrice in my cart, for a start.

[QUOTE=194240;Ray Borduin]If you remove it from the TotalPrice, then you can add it as a charge instead by using the total of the Surcharge column.[QUOTE]

If I remove what?

I don't have a Surcharge column. :( I thought columns were product data - populated by static or database values? Name, Description, Quantity, Price...what value would a Surcharge column have in this scenario? In other words, how would it be populated?

  Once you add the charge, you can add whatever label you want to it. The default "Charges" text is just text on the page that is freely editable.  

I don't know how to add the charge.

  If you want to sign up for a premium support ticket we can get through all of this in an hour session and I can answer any remaining questions and make sure it is all working correctly.  

This isn't a technical support issue I am simply asking how to achieve particular functionality, which eCart is well capable of. I was under the impression that it was "FREE {outstanding} TECHNICAL SUPPORT" (http://www.webassist.com/dreamweaver-extensions).

From what I can see, and maybe it's a bug with my version I'm not sure, there is nothing in the charges section that applies to adding 5% to the price of items from a certain category only.

These are the calculations that I currently have:

TotalWeight - [Weight] * [Quantity]
TotalPrice - [Price] * [Quantity]
FullDetails - [Quantity] . ' ' . [Name] . ' (' . [ID] . ')'

I'm looking for guidance on how to get eCart to perform the 5% calculation/charge.

Oh, and I need to run the ckeckout wizard and get all this saving to database AND get it communicating with SagePay so I'm pretty sure that you'll be getting plenty of Premier Support ticket sessions out of me in the future.

Hope you can help. Thank you.

PS. Jason would have had this sorted first post (no offence), no questions asked. I just need help on how to configure eCart. Nothing more.
