Unique quantity for each attribute

[Pengus]

Hi, I'm running a webshop selling spices. The attributes for my products is different weights with different prices.

Example rollist:

Spice 1kg ( 5$ )
Spice 2kg ( 8$ )
Spice 3kg ( 13$ )

My question:

How do I configure my shop so that different weights will draw different amounts from my stock.

Example: I set the quantity for "spice" to 300 (if I have 300kg in stock).

If someone chooses to buy 1kg spice, only 1 will be drawn from the stock (which goes 299)

If someone chooses to buy 5kg spice, 5 should be drawn (295).

The only way I can think of to do that would be to make 1Kg of spice the 'product', with a quantity box the customer could use to specify how 'many' he wants to buy.

Someone else may have another possibility.

I agree with stevesh--create a different product for each attribute set. There are a number of web-based inventory management and accounting packages that can be used to exercise more control over relationships between products--in my opinion this is cleaner than trying to manage stock directly within zen-cart.
