We need a script that a customer puts the height, width and length of their room into a form and then the script dynamically generates the amount of KW required to heat that room. The script must generate the result without having to press submit on a button etc.
There should be a drop down box on the form, so the customer can select either metres or feet for the dimensions of their room and then input their figures. The script will then do the following calculations :-
height in metres x length in metres x width in metres = m3
m3 divided by 14 = KW required to heat the room
height in feet x width in feet x length in feet = resul
result divided by 500 = KW required to heat room
In addition to this, we want their to be another drop down box for the level of insulation they have in their room. If they select average (default option) it will use the calculations above, if they select well insulated or poor insulation it will use a slightly different calculation. (to be supplied)
We have 2 sites that we can share with the winning bidder that already have this script in place, so you can see the kind of thing we are looking for.
I have attached mock up image of what the form would look like.
