Multiple option and price adjustments

[st_man]

I am having a problem with my present ecommerce solution and am looking at osCommerce.  Maybe it is built in or maybe there is an addon I can get.

Issue:

I have products that have 2 or more options.
2 of those options affect the price. Lets call them size (small and large)and color. (Some colors cost more than others)
Problem:
When someone chooses the small option then goes to the color it will add on to the amount depending on the color. That's fine.
The problem is if the large is chosen the color up charge needs to be larger but it is staying the same as for the small.
The program has a % upcharge option but it calculates it off the original price (the price for the small).
I need an options procedure the re-calculates whenever an option is chosen or changed and uses the new option one $ (large) in the option 2 add on calculation.

Does anyone know if this is possible?  How?  An addon, code development (do you know how?), etc....

 

Thanks in advance

Hi Stan,

 

So you've got these options with choice of values:

 

Size:

 - small

 - large (if this is chosen increase price of colours by 20%)

 

Colour:

 - blue $12

 - green $13

 - yellow $14

 

This is what you're saying, correct? When large is chosen you want the prices of the colours to increase by a set percentage.

The standard osCommerce attributes won't do that. It allows you to enter "fixed prices only" for each product attribute you create.

 

Why not just charge extra for the large? Example:

 

Size:

 - small

 - large $3

 

Colour:

 - blue $12

 - green $13

 - yellow $14

 

I did a search of the add-ons for "attributes", but at a glance I couldn't see any that will do what you want (not from their description anyway). Other forums members might know.

 

There is one addon "Child Attributes" here http://addons.oscommerce.com/info/8352/v,23. In the description it mentions options like yours but nothing about how it calculates the attributes prices. Maybe post a question in the add-on's support forum http://www.oscommerce.com/forums/index.php?showtopic=384028. The creator of the add-on maybe able to assist.

 

Other than that, you may need to get it coded for you.
