attribute priced by length

[kobra]

where they require that customers can input height and width requirements individually and the shop calculates the price accordingly

That is what was described earlier

i.e. on the product page the customer enter his dimensions into a text box, say 20 x 22.7mm and clicks update and the prices is worked out by attributes that are setup already.

Thanks again for your reply kobra!

The way I understant it, the solution you're suggesting means the customer inputs their height + width in a text field and then, on their own, multiplies the values and if they have 2x2m, they get 4sqm and inputs 4 as quantity.

That's still a little too much work for this the customers of this site - call them lazy, but that's how it is! They would need one box with width and one with height (and perhaps a button to click with "calculate price" or similar, where the system adds the dimensions and outputs the price based on the sqm price). The product is wallpaper, so it's likely to be quite exact also, for example a customer wants a dimension of:

340cm width
250cm height

If price per square meter is £10, the final price would be £85, as dimension is 8.5sqm.

It seems to me that would be a tad more complicated ;)

They are calculated from attributes
attribute A = length
attribute B = width
partial/decimal lengths/widths make it complicated...whole values easier

Dear Kobra(),

Sorry that I was unclear.
Allow me to explain price calculation first:
X - price factor
B - base price
W - width
H - height
SellPrice = (W*H*X) + B
So SellPrice depends on dimensions of article multiplayed with 'price facor' plus some base price.
What I did:
- I set article price to B.
- I set price to be calculated from attributes.
- I defined two attributes:
- Width (text)
- Hight (text)
- I set price by attribute. I think here I did something wrong... or I did not 'told' system to handle it in proper way. When I use different values for Width and Hight I still get same price calculated... as both attributes would not be multiplayed with eachother.

Is this more clear or did I missed some?

DaNew,
What is this?
What type of dimensions do you sell in?

Kobra,

Dimension used for sale is piece. One piece (a window) can have different dimensions.
I found out relation between size of the window and its price (that's formula described in my previous post).

Another approach could be: not to sell by piece but square meter. But the problem with this approach is that price by square meter decreases when square area increases. So then still some fixed price should be added...
That's why in my formula you will find a 'base price'.
