Link Web Form to Excel

Project Description:
Link Web Form to Excel Spreadsheet

I have attached a spreadsheet. The goal is to be able to enter data into a web form (on the internet) and have the data automatically populate the spreadsheet wherever it resides. I do not know whether there is a better way to do this, which would be great. Maybe the user inputs information into a web site and the data resides on a database where I can access and import into a spreadsheet.

The user must be able to select a date (either from a popup calendar or list) and then populate the fields on the form, click save or submit which will update the spreadsheet.

Additionally, I need the website to have security restrictions so that a user can enter an ID and password.

Finally, if someone has the background to also allow interactive graphs on the website (I will have tpo figure out which graphs) that would be great.

In your bid, please indicate whether you can do just the linking of web form to a spreadsheet, a database, or whether you can also do the graphing. Also, please describe what you will do specifically instead of some responses that I have received befroe saying "we can do it".

If you can take the attached spreadsheet and show me that you can actually do the project (even if it is just a sample) that will help me in my decision.
