Embed spreadsheet style data in website

Hi,

I have a simple spreadsheet that I would like to use in a website and would like to know what the best way to implement this would be.

The basic idea is the user enters a number in one field (roof area) and the results are displayed in a number of other fields. The only type of formulas are simple cell A + cell B /3 etc…

It is also imperative that only the one cell where the user enters the data is editable.

I have limited experience in sql and php from a couple of years ago at uni and was wondering if there is a simple way for such a simple spreadsheet to be incorporated into my site.

you can find the spreadsheet here:

Thankyou, if im not being clear i apologise and will attempt to elaborate.

It sounds like you are trying to make an interactive form which is better suited for Javascript. This is one I made a few months ago.
Your welcome to use this code for inspiration:

Incidentally, if you need to do this on the backside, the php would be very similar to this. The syntax is a little different.
