Another example - http://www.glasssplashbackuk.co.uk/Quotation.aspx

the calculator will be located on its own page. be able to produce a price based on the following -

1. User selects required shape (shape prices can be changed from the backend control panel)

2. User inputs height x width (a max height x width can be set from the backend control panel)

3. User then inputs number of (using a drop down box and price per item can be changed from the backend)

6. add to cart - full details must be added to shopping cart for the order confirmation.

7. from cart keep shopping - rests the splashback pricing calculator for next item.

Notes -
1. running throughout the price calculator page tooltips will give further information to what each thing (input) is.
2. must be in keeping with current site style. which is simpler to http://www.easyjquerygallery.com/ . the style, look and feel to this calculator is KEY!!! backend can look crap, but it must work.

I'm sure there will be some small additions and tweaks to the brief, but you get the idea.

Any questions please message me.

Thank you,
