Why is my table not calculating postage vs weight correctly?

[DonegalPaul]

Basically, I was putting some finishing touches to my proposed online shop (for now anyway) and was under the impression that if i attach a weight to each product i can then define weights and prices in the shipping module.

When i put the following in the table rate section, i thought that 0.1:1.99,0.25:2.75,0.5:3.20,0.75:4.25, meant that 0.1kg = £1.99, 0.25kg = £2.75 etc etc but its not tallying up when i test it.

Someone please tell me what im missing as i just can't see it

i seem to have gotten it working now, by making 1.1:1.99 mean £1.99 for up to 100g, seems strange but works.
